The rate of the reaction between sodium thiosulphate and hydrochloric acid Introduction In this experiment, I will use sodium thiosulphate plus hydrochloric acid to see how the rate of reaction change, by heat the sodium thiosulphate before add the acid. The equation of sodium thiosulphate plus hydrochloric acid is : Sodium thiosulphate+Hydrochloric acid › Sulphur + Sodium chloride + Sulphur dioxide + Water Aim To see how temperature affects the rate of the reaction between sodium thiosulphure and hydrochloric acid to form sulphur. Prediction If the temperature of sodium thiosulphate is higher, the rate of sulphur formed will be faster, that mean the time of reaction will be shorter. On the opposite side, if the temperature of the sodium thiosulphateis lower, the rate of sulphur form will be slower, that mean the reaction will be longer. Scientific background The rate of reaction always affect by the temperature, concentration of the solution and the subdivision. Temperature: If the...
