To investigate how the rate of the reaction between Sodium Thiosulphate and Hydrochloric acid can be altered. PLANNING Sodium thiosulphate and hydrochloric acid are two clear coloured chemical liquids. When reacted together they produce sodium chloride, water, sulphur and sulphur dioxide. When they react the solution turns cloudy and that is when the cross disappears and shows a reaction has taken place. The cross disappears as the reactants forms sulphur dioxide, this is what turns the solution cloudy. I could change many key factors to investigate the rate of reaction between Sodium Thiosulphate and dilute hydrochloric acid. These key factors consist of Temperature, concentration or having a catalyst. For my experiment the independent variables I have choose to investigate is temperature. AIM: To investigate if temperature affects the rate of reaction between sodium thiosulphate and dilute hydrochloric acid. PREDICTION: I predict that the higher you increase the temperature of the sodium thiosulphate the faster the...
