Crummy Details

Well this is what i did for my epxeriment
- researched info
- bought materials
- followed my method
- got information to back up my results

Well the vingear lost weight because the acetic acid int he vingear reacted with the copper oxide and issolved it.
The Bleach formed all those green spots which is actually called verdigris because the chemical sodium hypochlorite reacted with the copper
THe lemon coppers los weight becuase the citric acid dissolved the copper oxide
The water did nothing

So thata just a sum up

Well you guys have seen the pics so that all from me

Awesome fungul pics

Look the cool fungus in hte garbage bag. Thank god we had plastic gloves. It felt rubbery. I named that white one with black spots cow. And i named the grey one cloud.

Pictures finally after 4 weeks

This is one of the copper pipes which were in the bleach solution. You can see all that powdersish spots on its and inside it too




















Look the spots are pretty much falling off

This is the copper pipe in the vinegar solution. it looks smooth inside the cup

Look how blue the vingear solution has gotten

This is all that digusting fungus./ bacteria which grew in the lemon solution

Whoops

I know I still haven't posted the pics. I will do it soon. i juts need to find the cmaera that i used. Well I was searching up info from my experiment and I have bad and good news. Well all the materials are supposed to react with the copper. However they react differently

The bleach contains Sodium hypochlorite which is a chemical compound consisting of sodium, oxygen and chlorine. This is really reactive with metals. When in prescence with copper it forms copper chloride. This is a type of verdigris which is the the green powdery stuff that formed.

The vingear reacts differently as it actually cleans the copper. It contains this acid which actually gets rid of the copper oxide which has formed. See when i started the epxeriment the copper had already oxidized because it was exposed to oxygen. But when I got copper pipes out of the solution it had become shiny because the copper oxide had disoolved. This is why the solution had turned bluey. Because the dissolved copper oxide had mixed with the vinegar solution which had water in it. Lemon is also acts similaryliy to vinegar i think. But I'm not really sure

I scrpaed off the greenish stuff ont he copper pipes which had been in the bleach solution. When I scraped it off the copper was shiny. I think because I also scraped off the copper oxide which is a browny colour. In one of my pipes there was also a hole.

My Dodgy Results

Omg measuring the copper pipes was disgusting
All of the Lemon Samples had this massive layer of fungus and bacteria on the top
I'll post the pictures soon
It was soo gross

Well for my Bleach result i do not know if they are legit because remeber how in my earlier posts i showed you that these bluey black powdery spot had formed. Well when I was observing I touched it and it came off straight away. So then I actually scraped some off and not only did the powdery stuff go but some of the copper piper brokes off and I could see a new shiny layer of copper.

The results I gave was the weight including the powdery stuff. I'm not sure if the powdery stuff is part of the degradation of the copper pipe. So maybe I should scrape it all off and then measured the pipe because then I would get totally different results.

Repete of Method

First my dad cut the copper pipe into 5 cm length sections with a saw. He cut 12 portions. I then labelled the clear plastic cups ,which were all the same size, with the names of the different solutions. The different solutions are the water and vingear, water and lemon juice, water and bleach and just water. I need 12 cups because it have to repete the experiment three times. to make it fair.

I then measured the water and lemon juice with a tablespoon. I put 3 tablespoons of water and three tablespoons of lemon juice. I also used a neurofen dropper to make it exact. I repeted this with the bleach and vinegar solution. For the cup with just water i put 6 tablespoons of water. The above steps were then repeted three times.

before I put the copper pipe sections in each cup. I measured each copper pipe section first. I then put one copper pipe section in each cup. i then put the cups in the chocolate boxes so that they wouldn't be tipped over as easily. They are all stored in the cubby shelf of my cupboard. After 4 weeks I am planning on measuring the copper pipes gain to see the percentage difference in weight. I'm not sure if it will be a gain or loss in weight.

To get the exact measurements of the weigt i used this awesome electronic scale which measures a point of a gram. How cool is that.

Climograph

This is my climograph

Three weeks since Experiment- Photos

I do not know i you guys can see it but in this bleach solution there some powdery blue spots forming on the copper pipe.

The liquid in the Vinegar solution has turned a shade of blue. I think this means that the copper is dissolving

Real Experiment Photos

I stored my cups in empty chocolate boxes so that they wouldn't fall easily. They looked more protected. And the boxes have been stored in the cubby spaces of my shelf. So its all good. Nothing has tipped over or fallen over yet. Yeah

This is my Scientific scale it meausres point of a gram. How awesome is that. Now I sound like a science geek. Oh well I've said more embarassing things in my life

The equipment that I used






- White King Bleach






- Lemon juice






- Vinegar






- Neurofen dropper - to get the exact amount






- Tablespoon measurer






- Scale that measure milligrams

Problemo Photos

Look the Washing powder will not dissolve in the water either

Crap look the Bi carbonate poder will not dissolve and mix in the water.

Trial experiment photos

This is what the copper pipe looked like in a week.
It has become brown

This is the trial bi carb solution. When I put mixin spoon in ti it felt so heavy

This is the trial expeirment with my vinegar solution.The Solution turned into a blueish colour in 3 days. Well, I did put alot of vinegar

My Maginificant Methods - hey looks its alliteration

So My new experiment is the 4 different solutions
water and lemon juice
water and vinegar
water and bleach
just Water
I've started my experiment and I'm going to upload some pictures
I said that before didn't i
Okay well I followed this method
1. Using a tablespoon, three tablespoons of lemon juice was poured into a clear cup
2. Using the tablespoon, three tabllespoons of water was poured into the same cup
3. In a different cup three tablespoons of bleach was poured
4. In that same cup three tablespoons of water was poured.
5. In a different cup 3 tablespoons of vinegar and 3 tablespoons of water poured
6. In another different cup 6 tablespoons of water was poured in a cup.
7. The cups were labelled with the different solutions and the above steps were repeated 3 more times.
8. The Copper pipe was cut into sections of 5 cm lengths
9. Each of copper sections' weight was measured and recorded
10. one section of copper pipe was placed in each cup full of solution
11. The above steps were repeated 3 times

So thats the method I followed and after four weeks I am going to again measure the weight of the copper pipe sections and see the percentage difference in weight. I'm not sure which pipes will gain or lose weight

It's now been almost 3 weeks

From my observations the cup full fo vinegar has turned blue. I think is because the copper is disolving.

The cups with the bleach solution have not changed colours but the copper pipes are get these blue solid powder spots. It looks like mutated chicken pox.

I can't even see the copper pipe the lemon solution

The pipe in the just water doesn't look like its made any physcial changes

I am going to upload the picture in 15 minutes

Major Problemo

So in the holidays me and my dad went to BUnnings. OMG never go to Bunnings with your dad. We were only supposed to get a copper pipe and a saw and we ended up with also 3 large pots for the garden, fertiliser, a new hose and new plants. Far out!!!!!
Well My dad finally finished cutting the copper pipes and I have 16 which is more than enough and each are 5cm. So they weigh around 15grams. The scale is pretty cool you can like weigh your rubber and stuff.
Well since i had four extra pipe sections I did a little trial you know to see if this would really work. So I made two extremely concentrated solutions for two pipes. One solution was practically made of 1 part water and 7 parts vingear and the solution was 2 parts water and 6 parts bi carbonate
Well obviously the bicarbonbate didn't dissolves but i thought when I do the actually quantities I would be fine
So i left the pipes in the solutions over night and the copper in the Bi carbonate soda changed from a copper colours to a brown colour and the Copper in the vinegar solution didn;t change colour by the soluation changed from clear to blue. I guess these were obvious signs that something was happening

So I started the real experiment with the washing powder, bicarbonate and vinegar
Major issue the bicarbonate and washing powder wouldn't dissolve in the little water and would just end up sinking to the bottom. THis wasn't going to work. My dad then suggested to put make more than half the solution water but then Ms Zhand said earlier that if their was alot of water results might not show

So I've now decided to screw the bicarbonate powder and dish washing powder. I am going to replace them with lemon juice and washing liquid. How smart am I. Liquid will obviously have no trouble mixing with another liquid. But I can't start the experiment till tomorrow. I still have to get Ms Zhang's ok and my dad still hasn't gone shopping.

Anyway This will take around 4 week to 5 weeks so I should be done by week6 which is 3 weeks before the major report is due which isn't too bad. I hope these copper pipes rust or show some change

Anyway byeee

Weighing the rust

Hi again

For measuring the rust I think I will measure the pipes with a scale where the lowest numebr on the sclae is 1 gram. However I think think I will need something more prescise that also measures milligrams because then the weights will be more varied and the varibale will be better controlled.

I'm think of measureing the pipes everyweek as well to show the rate of rusting. But I ;m not sure if this will affect the overall results at the end of the 4 weeks.

So far this is my idea.

For my discussion I'll probably add how we try to prevent rust in pipes like the different devices and chemicals used.

Im back again

I made another mistake.
THe independant variables are:
- size of copper pipe portion
- amount of solution
- ingredients in solution
- time
- container
- location
The dependant variable:
- the amount of rust
Whoops I know I am very careless
For mearsuring rust I think I will still do it by measuring the weight of the copper pipe before and after the experiment. I can't easily control the variables when scraping the rust off or looking at the rust and deciding which has more by my eye. This wouldn't be a fair test.
I think I might have to use some special scale that hopefully the school has but I'll check on it and write what I will use, tomorrow

But Bye for now

Final Decision

In the las post I think I made a few mistakes so I'm going to fully Explain my experiment now.
The hypothesis of my experiment is that mor acidic washing substances wll cause copper pipes to rust more.
In may experiment I will cut up a copper pipe into a equal portions and place each portion into a tub of solution for 4 weeks. The different solutions will include:
Vingear Solution: 50% Vinegear and 50% water
Bi Carbonate of Soda Soultion: 50% Bi Carbonate of Soda and 50% water
Washing powder Solution: 50% Washing powder and 50% water
The independant variables will be the time frame, the tub size, location amount of solution and the size of the copper pipe.
The depedant variable will the be the different ingrediants in the solution and hopefully the rust
During the experiment I'll take photos. This experiment will take four weeks and instead of doing two other tests afterwards I will do all three of the experiments at the same time because of the time frame. By doing the experiment three times it would more fair and I could get better results. After the experiment is finished I will measure the amount of rust and put the result on a column graph.
But I'm still of thinking of ways to measure rust I have a few ideas. These indclude
- Weigh the copper pipe before and after the experiment
- Scrape the rust off and measure it
- I could visualy decide
I think I'll probably weight the copper pipe before and after the experiment because it is more appropriate and accurate. I wouldn't be able to control my varibales if tried to scrape the rust of because I might scrape too much or little and some dust may still be in the scraper.

What do I do

Now I think I've just confused myself
My point of the experiment was to see which washing substance would cause the most rusting. My hypothesis is that more acidic washing susbstances will cause more rusting. Now I'm going to change my experiment again. I will stilll use same sized copper pipes but I will increase the concentrations in my solutions. So I'll probably use
Vingear Solution: 50% Vingear and 50% water
Washin powder soloution: 50% washing powder and 50%water
Bi carb Solution: 50% Bicarbonate of soda and 50% water.
The time frame, amount of soloution, tub size, copper size and location will remain constant which is the dependant variable.
The independant variable will be the different substances int he solutions.
I hope this makes more sense.

Oh Dear

Ms Zhang just told me that the concentration of my solutions wouldn't show much of a difference. But the aim of my experiment is to see the difference in rusting of copper pipes caused by the different washing solutions. Maybe I should chnage my experiment where I see if the more concentrated my solutions get the more rusting occurs. Then I could compare the differences. So would compare the difference of rusting with different concentrations of vinegear, Bi-carbonate of soda and washing powder solutions. This is what I'm going to do I'm going to label the different concentrations with different levels, from less concentrated to more concentrated. Here is an e.g. if none of you get what I'm saying:
Vinegear Solution levels
Level 1 : 75ml water and 25ml vingear
Level 2: 50ml water and 50ml Vingear
Level 3 25 ml water and 75 ml Vingear
All together I'll have to have 9 tubs
Pls leave comments on how I could improve

I'm BACK

Okay Well I've been thinking more about my experiment. This is what I think I going to do.
I'm going to get a copper pipe and cut it up into equal portions. Then I'm going put these portions into individual ice - cream tubs or some sort of bucket with a solution.. Even though the solutions will be different they'll still be the same quantity. For e.g.
Water solution = `100 ml
Vingear solution = 15ml of vinegear and 85ml of water
Bi carbonate solution = 15g of Bi carbonate soda and 85ml of water
Washing powder solution = 15 g washing liquid and 85 ml of water
I'll probably keep the copper tubes in the solutions for a week and take picture of the changes in the material everyday. At the end I'll compare the difference in the rusting.
so I'm going to keep the amount of solution, size of copper pipe portion and amount the days in the solution the same. The things that won't be the same will be the different solutions and hopefully the rusting.
I'll probably have do the experiment three times so it will be fair and I'll also get better results.

OMG

Well seeing as MS Zhang has just reminded that our blogs are due next thursday I think i might get a move on. Well it did some research and found a few ideas. Here are some of them
- Affect of sound on the growth of plants
- In what environment does bread last the longest
- effectiveness of different hand sanitzers on killing E. Coli and Serratira bacteria
- Effects of salt water on plants
- Effects of different washing substances on pipes
- Househol vs professional carpet cleaning

So ultimately I chose the effects of different washing substances on pipes
I'm thinking of like placing small tubes of copper pipes into different solutions such as water and Bi Carbonate of Soda, water with vinegar and water with wahing powder. I thinking that maybe the pipe will go rusty. So I might change the experiment on which different houshold substances cause the rusting of copper pipes the quickest
