CHEMISTRY INVESTIGATION: HCl CONCENTRATION ON MARBLE CHIPS Planning Introduction & Aim The investigation we are performing is about the concentration of hydrochloric acid on powdered marble, and what effect it has on the reaction and the amount of gas produced. My aim is to demonstrate how the changing concentration of the hydrochloric acid affects the amount of carbon dioxide produced when it is added to marble chips. We have performed similar experiments before which will help us to know which safety precautions to take and sensible measurements of the substances involved. The chemical reaction which occurs in my experiment is: 2HCl + CaCo CaCl + H O Factors which may affect the experiment When a reaction takes place the particles of the reacting substance must collide with each other and the activation energy must be reached for the reaction to occur. The reaction will occur if there is a collision between the particles and they produce...
