Science Investigation GCSE Chemistry Practical No 1 How does the concentration of acid affect the rate of reaction with magnesium? Aim: To find out how the concentration of hydrochloric acid affects the rate of reaction with magnesium ribbon. Hypothesis: I think that the lower the concentration of Hydrochloric acid, the slower the rate of reaction with Magnesium ribbon. The reason why is because there are less particles in the same volume so less collisions are possible every second, therefore less effective collisions will occur. Preliminary work: I did an experiment before to find out how the concentration of hydrochloric acid affects the rate of reaction with Sodium Thiosulphate. Preliminary work backs up this hypothesis. Because, when doing the practical previously, I found out that the rate of reaction between Sodium Thiosulphate and Hydrochloric acid depends on the amount of concentration, which becomes faster with a higher volume of concentration. Mg + 2HCL MgCl2 + H2 This equation shows the reaction that...
