Sodium thiosulphate investigation Aim: To investigate how the concentration of sodium thiosulphate as it is diluted with water and then added to hydrochloric acid, affects the rate of reaction. Prediction: I think that as I dilute the sodium thiosulphate with water and then add it to the hydrochloric acid, the time for the rate of reaction will increase. I have followed a special theory for this. The theory is the collision theory, which states, as you increase a substance there are more particles in it resulting in more collisions. This theory can also work vice versa because in this experiment we will be decreasing the concentration of sodium thiosulphate resulting in less collisions, therefore extending the time for the reaction to take place. In a low concentration, the particles will be few and widely spread. This means that the number of reactions will be limited because fewer particles will meet. At higher...
