Aim: - To find out how fast the solution turns yellow, and how long it takes for the cross to disappear, using the different factors which will affect the rate of reaction: Concentration, Particle size, Catalyst, Temperature. Previous Knowledge: - The higher the consistence of the Dilute Hydrochloric Acid, the faster the solution mixed with Sodium Thiosulphate turns cloudy. Here is a word equation to prove the rate of reaction: Sodium Thiosulphate + Dilute Hydrochloric Sodium + water + Acid Sulphur chloride Here is a chemical equation to prove the rate of reaction: Fair test: - In order to make my experiments as fair as possible I will carry out the following: * I will make sure there is the right amount of Acid and Thiosulphate for the specified experiments. * I will alternate the concentration of acid when needed for the specified experiments. * I will use the same volume of Acid and Thiosulphate for all of my experiments. * I will...
