Investigation:
How does the concentration affect the rate of a reaction?
Aim:
To investigate the effect of concentration on the rate of a chemical reaction between sodium thiosulphate solution and hydrochloric acid.
Reaction:
I will investigate the reaction between different concentrations of sodium thiosulphate solution with hydrochloric acid.
Na2S2O3(aq) + HCL(aq) = S(s) = H2O(l) + SO2(g) + NaCl(s)
(sodium thiosulphate + hydrochloric acid = sulphur + water + sulphur dioxide + sodium chloride)
Background Information
There are three ways of measuring the rate of reaction:
