SHURREEN MILES 10.G REACTION OF CALCIUM CARBONATE GCSE COURSEWORK AIM: To investigate the factors affecting the rate of reaction of calcium carbonate (limestone) with hydrochloric acid. SCIENTIFIC KNOWLEDGE: When you add hydrochloric acid to limestone it reacts giving off gases which is carbon dioxide, the concentration of the acid will also affect the rate of reaction like the surface of the limestone also if the water in the experiment is warm or cold. The scientific equation is CaCO3 (S) + 2HCl (aq) - CaCl2 (aq) + H2O (1) + CO2 (g). Example of the concentration is that when the concentration is in creased the particles will be closer together and when the solution is made warmer the particles move faster. PREDICTION: I predict that as the temperature of the acid increases, the rate of reaction will increase. This is because, when a liquid is heated, the particles move faster and have more...
