Science Coursework - Preliminary work Aim: My aim is to investigate how temperature affects the rate of reaction in the reaction of Sodium thiosulphate and hydrochloric acid. I will do this by repeating the experiment a number of times and changing the temperature. Plan: I will put Sodium thiosulphate in a test tube in a water bath of distilled water because it is purer than tap water and by using a Bunsen burner I will heat it to the desired temperature, which I will measure using a thermometer. Once the Sodium thiosulphate has been heated I will add it to the Hydrochloric acid, which will be in a conical flask. I will draw a cross on paper and place this under the conical flask, I will draw the cross using a black marker so that it is fully visible and the same cross will be used for each experiment. I will start...
