Sodium Thiosulphate Reacts With Acid How Does Temperature Affect The Rate of Reaction? When sodium thiosulphate reacts with hydrochloric acid one of the products is yellow sulphur. The sulphur forms a precipitate in the solution and makes it go cloudy. The chemical formula is shown below: 2HCL + Na2 S2o4 2NaCL + S02 + H2O + S Aim The aim of this investigation is to find out and observe how temperature affects the rate of reaction. I am going to do this by investigating the changes caused to the solution of hydrochloric acid and sodium thiosulphate. I am going to mix hydrochloric acid with sodium thiosulphate and time how long it takes to react at different temperatures. Science Knowledge The rate of reaction is the speed at which a chemical reaction precedes, expressed in terms of the amount of product formed or the amount of unit's time taken for a certain reaction to occur (usually in seconds)....
