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.

Do you think that 15mL or 15 g of any solution is going to be enough to look at a difference? Whilst this sounds good, perhaps... limit your variables down and see maybe JUST one solution... and see how you go? And with the one solution, you can have differing concentrations of it?
