rate of reaction between Thiosulphate (Na2S2O3) and Hydrochloric acid (2HCl) We are planning an investigation to measure the rate of reaction between Thiosulphate (Na2S2O3) and Hydrochloric acid (2HCl) the equation for the experiment will be Na2S2O3 +2HCl--> 2NaCl+SO2 +S?+H20 The rate of reaction is the speed at which reactants are converted into products. The rate of reaction is usually expressed in terms of a change in concentration of one of the participants per unit of time. Rate = [ ]/ t You can change the rate of the reaction by: * Changing the concentration of the Thiosulphate * Adding a catalyst * Changing the temperature * Changing the volume of the Thiosulphate * Changing the volume of the Hydrochloric acid * Changing the surface area * Gas/pressure Method The investigation will be performed in a safe way by: 1. Wearing goggles at all times to protect eyesight. 2. Making sure all equipment is clean and there are no other chemicals...
