Factors affecting the rate of reaction between Sodium Thiosulphate and Hydrochloric acid. Aim: In this experiment I aim to measure the affect of concentration on the rate of reaction between Sodium Thiosulphate and Hydrochloric acid. HCl + Sodium ThiosulphateSodium Chloride + Sulphur Dioxide + sulphur + water HCl + Na2S2O3 NaCl + SO2 + S + H2O Prediction: I predict that with increasing concentration, of Hydrochloric acid, the rate of reaction will increase. I think this because increasing the concentration of a substance in solution means that there will be more particles of that substance. When there are more particles in a reaction, the rate of reaction is increased because there are more particles to collide and so the reaction takes place quicker. (In this case the formation of Sulphur which turns the colourless substance cloudy.) I also predict that the rate of reaction and the concentration will be proportional. i.e if you...
