An Experiment to Investigate the Effect of Concentration on the Rate of Reaction Shehzad Ali Charania An Experiment to Investigate the Effect of Concentration on the Rate of Reaction Planning 1. Aim This experiment's aim is to discover the effect the concentration of a reactant has on the rate of reaction. We will be using sodium thiosulphate and hydrochloric acid. This is because the speed the sulphur (a product) is produced is quite easy to measure and covers the aim of the experiment sufficiently. To try to investigate the aim, w will change the concentration of the sodium thiosulphate and repeat this twice before taking an average and recording our results. The equation for this experiment is: Na2S2O3 + 2HCl --> 2NaCl +SO2 + H2O + S The word equation for this experiment is: sodium thiosulphate + dilute hydrochloric acid --> sodium chloride + sodium dioxide + water + sulphur 2. Preliminary Experiment The preliminary experiment involved using the chosen...
