Rates of reaction
Aim: To investigate how the concentration of hydrochloric acid effects the reaction between hydrochloric acid and sodium thiosulphate.
Introduction: I will be conducting an experiment on the rate of reaction for my gcse coursework. I will be doing this coursework for a period of two weeks. We will be reacting sodium thiosulphate with hydrochloric acid. And i will be investigating how the concentration of hydrochloric acid effects the reaction between hydrochloric acid and sodium thiosulphate. When sodium thiosulphate and hydrochloric acid are mixed, A yellow precept of sulphur is produced the solution becomes increasingly difficult to see through as more and more sulphur is formed.
Prediction: I think that as the amount of sodium thiosulphate is decreased and the volume of water is increased, the reaction time between it and hydrochloric acid will increase. This is because when concentration of a substance increased, it reacts a lot quicker due to there being more particles that want to react with each other. Reactions can only happen when the reactant particles collide, but most collisions are not unsuccessful in forming product molecules. Water has been introduced
