I am currently doing an experiment.
The experiment is to investigate the dependence of reaction rate on conc. for the reaction between sodum thiosulphate reacts with dilute acids
By varying concentrations of thiosulphate and H+ respectively in 2 experiments.We can easily find that speed of reaction is proportional to conc. of reaction.
the thing I want to ask is
Drops of thiosulphate 1 2 3 4 5 6 7
Drops of water 6 5 4 3 2 1 0
Drops of H+ 7 7 7 7 7 7 7
Drops of water 2 2 2 2 2 2 2
what do we need to make the total volume constant for the reacions?
is it because to standadize the experimentally condition , each time only 20cm3 thiosulphate solution is used.Addition of water enables different conc. of thiosulphate all at 20 cm3?
I am really frustrated .
Thanks
