Aim - To investigate the effect of concentration on the speed of the reaction between hydrochloric acid and sodium thiosulphate. Prediction: My prediction is, the higher the concentrations, the faster the reaction will occur in my experiment to make the x on the sheet on paper disappear. When there is more concentration, the molecules gain kinetic energy & the process of collision occurs. This causes the reaction to happen more rapidly therefore making a cloudy substance much quicker. Hypothesis Sodium thiosulphate has the formula Na2S2O3. It resembles sodium thiosulphate, Na2SO4, with one less oxygen atom and one more sulphur atom. The additional sulphur atoms can be driven out by an acid. Equation Na2S2O3 + 2HCl S + 2NaCl + SO2 Sodium Thiosulphate + Hydrochloric acid Sulphur + sodium chloride + sulphur dioxide Variables Independent Variable - factors to be changed: The concentration of sodium thiosulphate solution will be adjusted to be tested at different molars. This is changing the ratio of...
