Reaction between Magnesium and hydrochloric Acid 2HCl(aq)+ Mg(s) Hydrochloric acid + Magnesium ribbon Aim My experiment will investigate the reaction between hydrochloric acid and magnesium. The aim is to establish the relationship between the concentration of the hydrochloric acid and the rate of reaction. Since the rate of reaction may also be affected by temperature and volume, to ensure a fair test, these will be kept constant, and only the concentration of hydrochloric acid will be varied. Prediction My prediction is that whilst keeping all other variables being constant, the rate of reaction will be proportional to the concentration of hydrochloric acid. The higher the concentration the higher the rate of reaction. This could be due to the number of molecules of hydrochloric acid being proportional to the concentration. The rate of reaction will be proportional to the number of acid molecules that are available to collide and react with the magnesium. The Collision Theory...
