Aim;

The aim of this lab is to investigate the rate on the reaction between sodium thiosulphate and Hydrochloric Acid, when the values of concentration and the temperature is either decreased or increased of the Hydrochloric Acid.

Background;

The definition of a reaction is when two or more reactants connect to form a new precipitate. The rate means how low/fast something takes place and it is the measurement of time and change that happens in a component. The rate can be used in any suitable measurements such as seconds, minutes and even hours. For these reasons the rate of a reaction means how fast/low it takes for the reactants to form a new precipitate.

Hydrochloric acid and sodium thiosulphate are both clear and colorless liquids, but in the reaction between them a precipitate of yellow and cloudy sulphur forms to measure the rate of the reaction. The aim is to time how long it takes for the reaction to form the actual
