The Disappearing Cross Background Information Sodium thiosulphate Na2S2O3 reacts with hydrochloric acid HCl as follows. Word equation Sodium + Hydrochloric -> sodium chloride + Thiosulphate acid sulphur + sulphur Dioxide + water Balanced Equation Na2S2O3 + 2HCl(aq) -> 2NaCl(aq) + S(s) + SO2(g) + H2O(l) When the reactants are mixed together the solution becomes cloudy because sulphur is precipitate. As the precipitate gets thicker, ink cross of a piece of paper below the flask disappears. The aim of this investigation is to study in detail the effect of a variable on the rates of reactions. Aims The aim of my investigation is to find out the effect of temperature on the rate of reaction. Prediction I predict that as temperature increases the rate of reaction will also increase. I think this is because the particles will have more energy and more collisions will occur. Scientific Knowledge Components affecting rates of reaction are temperature, whether a catalyst...
