Plan Aim: For my coursework investigation, I aim to investigate the effect of concentration on the rate of reaction. The Reaction which I am going to use, is that between: Sodium thiosulphate solution and dilute hydrochloric acid The chemical equation for this reaction is as follows: Na2S2O3 (aq) + 2HCL (aq) -------> 2NaCl(l) + H2O (l) + SO2 (g) + S(s) Sodium + Hydrochloric ---------> Sodium + Water + Sulphur + Sulphur thiosulphate acid chloride dioxide Research Primarily, I must summarise the key bits of information and the key theories that are relevant to my investigation. Chemical reactions Chemical reactions are processes, which leave us with new substances. In a chemical reaction, the materials, which we put in at the start, are called the 'Reactants'. These reactants are changed in the chemical reaction, into a new substance; this substance is called the 'product' of the reaction. For a reactant to change into a...
