A method of preparing sodium thiosulphate is to react sodium sulphite with sulphur. Method Dissolve 3g sodium sulphite (Na2SO3) in 15 cm3 hot water and add 1g sulphur (S8). boil the suspension until nearly all the sulphur has reacted. Filter hot (using a glass filter funnel plugged with a small piece of cotton. Ensure that the tip of the funnel is heated as well as the container for the filtrate) and evaporate the filtrate until crystallization starts. Cool and filter the crystals by suction. Dry the product in a warm oven (keep below 480C). EquationNa2SO3 (s) + 1/8 S8 (s) -------H2O/1000C--------> Na2S2O3 (s)
