GCSE Chemistry Coursework. Practical Assessment. PLANNING EXPERIMENTAL PROCEDURES. TITLE: The effect of temperature on the rate of reaction. PROBLEM: We must produce a piece of coursework investigating the effect of temperature on the rate of reaction when Hydrochloric acid is added to Sodium Thiosulphate. The rate of reaction is the rate of loss of a reactant or the rate of formation of a product during a chemical reaction. Reaction rates are measured by dividing 1 by the time taken for the reaction to take place. I know that you get a yellow precipitate of sulphur when Hydrochloric Acid is added to Sodium Thiosulphate. The solution becomes cloudy and you cannot see through it, Hydrochloric Sodium Sulphur Acid + Thiosulphate = (precipitate) I am investigating what would speed up this reaction. BACKGROUND KNOWLEDGE: CONCENTRATIONS. Moles are a way in which concentration can be measured; the higher the concentration the higher the density...
