    I'm having trouble in creating a table of results for the rate of reaction of sodium thiosulphate and hcl, focusing on concentration. It's the experiment where you time how long it takes for the solution to go cloudy so the cross beneath becomes invisible.

    I was thinking something like this:

    ------------------------------------Time/s
    Concentration 1/mol dm^-3-----x

    Concentration 2/mol dm^-3-----x

    Concentration 3/mol dm^-3-----x

    Thoughts?

    Few questions you should ask yourself,

    1) out of the two reactants, the thiosulphate and the HCl, which concentrations are you changing? if so, how are you changing them?

    2) Is the same cross on the same piece of paper being used? is there consistency in the way the time is recorded, i.e. the timer is stopped at the first instance when precipitation occurs or until the cross totally becomes out of sight.
