THE EFFECT OF CONCENTRATION ON THE RATE AT REACTION BETWEEN ACID AND CALCIUM CARBONATE (MARBLE CHIPS) My aim of my investigation is to find out how changing the concentration of an acid affects the rate of reaction between calcium carbonate (CaCO3) and Hydrochloric acid (HCI). To make it a fair test, I am only going to change the concentration of the acid. I am going to keep the volume of acid, the mass and size of the marble chips and the temperature of the acid the same to ensure a fair test. This is because by changing any of the above, I will change the conditions and therefore the results will be inaccurate and the rate of reaction will be affected. The products of the reaction between hydrochloric acid and the marble chips are calcium chloride, water and carbon dioxide. CaCO3 (s) + 2HCI (aq) CaCI2 (l) + CO2 (g) My prediction is...
