Rates of Reaction Coursework Aim: My task is to investigate how the rate of reaction between sodium Thiosulphate and Hydrochloric acid depends on the concentration of sodium Thiosulphate. Theory & Background: If the concentration of any reactant in a solution is increased, the rate of reaction is increased. Increasing the concentration increases the probability of a collision between reactant particles because there are more of them in the same volume. I will measure the following: 1. Sodium Thiosulphate solution. 2. The Distilled Water. 3. The dilute Hydrochloric Acid. 4. Time for X to disappear -(stow watch). The Variables: 1. Amount of Sodium Thiosulphate 2. Distilled Water 3. Hydrochloric Acid - Volume kept same 4. I will also use the same flask every time. FairTest Fair test: To make this a fair test, we need to make sure we do a number of things. In this experiment we are trying to find the rate of reaction...
