Effect of concentration on the rate of reaction between Sodium Thiosulphate and Hydrochloric acid Aim: The aim of the experiment is to find out if the concentration of Hydrochloric acid effects the rate of reaction between sodium thiosulphate and hydrochloric acid. Equation: Na2 S2 O3(aq) + 2HCL(aq) H2O(1) + SO2(g) + S(s) + 2NaCL(aq) Sodium thiosulphate + Hydrochloric acid Water + Sulphur dioxide + Sulphur + Sodium Chloride Preliminary work: The main aim of this experiment is to find out about concentration. This means that I will require having knowledge on the subject. Concentration is the number of molecules of a certain substance in a solution with other substance. An easy way of explaining this is with Ribena drink. When you first pour the ribena into a glass the ribena is 100% concentrated. After that you then add water, the water dilutes the ribena and alters the concentration of it. This means that the drink...
