How does temperature affect the rate of reaction between sodium :: GCSE Chemistry Coursework Investigation

How does temperature affect the rate of reaction between sodium thiosulphate and hydrochloric acid? Aim: The aim of this experiment is to find out how the temperature affects the rate of reaction between sodium thiosulphate and hydrochloric acid. Prediction: I predict that the higher the temperature of the solution the faster the reaction will take place because the particles will collide more when the temperature rises. Plan Apparatus: Measuring cylinders Tripod Bunsen burner Heat proof mat Gauze mat Thermometer Conical flask Water (30ml) Hydrochloric acid (5ml) Sodium thiosulphate (20ml) Piece of paper with X on it By lianne milbanke Pliminary results: I decided to do some preliminary work because then I could see what amount of Sodium thiosulphate, Hydrochloric acid and Water I needed for the reaction, I tried it 5 times before I found one that was not too fast and not too slow. ---------------------------------------------------------------- Sodium thiosulphate Hydrochloric Water (ml) Time (sec) (ml) acid (ml) 50 5 0 36 40 5 10 51 30 5 20 70 20 5 30 133 10 5 40 395
