An investigation write-up. Aim: to find the factors that affects the rate of reaction between dilute hydrochloric acid and sodium thiosulphate. plan: firstly I will get a container of dilute hydrochloric acid and one container of sodium thiosulphate each measuring 25cm cubed, I will mix the two together and measure how long it takes for them to react. I will do this by placing a piece of paper with an x clearly marked on it underneath the mixing container, then starting from when the reactants are mixed and finishing when the x is no longer visible I will time the reaction. I will make the test fair by using the same x and using different containers (there may still be reactants in the containers afterwards) I will also monitor the room temperature at the start of each reaction. Key factors in the experiment will be the concentration of the thio and the...
