Investigating the effect of changing the concentration on the rate of reaction

Plan

I am going to investigate the effect of changing the concentration of sodium thiosulphate on the rate of reaction.

sodium hydrochloric sodium water sulphur sulphur

thiosulphate + acid (aq) + (l) + (l) + dioxide

(aq) (aq) (g)

Na2 S2 O3 + 2HCL 2NaCl + H2O + S + SO2

I have done previous work on this investigation, in class & from past preliminary work.

In my preliminary work we have done a similar experiment, but to find out what effect temperature had on the rate of reaction between sodium thiosulphate, hydrochloric acid & water. We used this past experiment for the basis of this experiment to find out what effect concentration had on the rate of reaction.
