Antoine Allen Investigate the rate of reaction between sodium thiosulphate and hydrochloric acid, when you change the concentration Aim The aim of this experiment is to investigate what affects the rate of reaction between Sodium Thiosulphate and Hydrochloric Acid. By using the bariable of sodium thiosulphate concentration Equations Na2S2O3 + 2HCl = 2NaCl +SO2 H2O + S Sodium thiosulphate + hydrochloric acid = Sodium Chloride + sulpur dioxide + water + sulpur Background research What is the most accurate way of obtaining the reaction rate between sodium thiosulphate and hydrochloric acid? The average rate of a chemical reaction, over a certain time, is equal to the change in concentration of the reactant or the product divided by the time taken. Which method you use depends on the type of reaction it is. One way of finding this out is by carrying the reaction out in a thermostatically controlled bath - i.e. one that you can control...
