How does changing the concentration of the Hydrochloric acid affect it reactions with Magnesium? Aim: The aim of our investigation is to see how various solutions of Hydrochloric acid react differently to Magnesium. Introduction: The two main substances that will be used during this experiment are as follows: Hypothesis: I predict that as the concentration of the Hydrochloric acid increases, the time taken for the magnesium to disappear decreases. So, the higher the concentration of the acid, the faster the reaction between magnesium ribbon and the hydrochloric acid will be. This would be because there were more acid molecules to react with the magnesium ribbon. I also predict that when the concentration of the Hydrochloric acid doubles, the rate of reaction also doubles. (Therefore, hcl is directly proportional to mg, hcl ? mg. ) Increasing the concentration of the reactants will increase the frequency of collisions between the two reactants. So this...
