Experiment to investigate the rate of reactivity between calcium carbonate and hydrochloric acid Introduction: The experiment taking place is between calcium carbonate [CaCO3] and hydrochloric acid [HCl]. Calcium carbonate, also known as marble, is a metamorphic rock. This is a rock that is formed over long periods of time under high temperature and pressure. It is also formed when carbon dioxide reacts with calcium hydroxide to produce calcium carbonate. Calcium hydroxide + carbon dioxide calcium carbonate + Water Ca(OH)2(aq) + CO2(g) CaCO3(s) H2O(l) When an acid reacts with a carbonate the products are salt, water and carbon dioxide gas. When hydrochloric acid reacts with calcium carbonate the products are calcium chloride, water, and carbon dioxide. The formula for this reaction is: Hydrochloric acid + Calcium carbonate Calcium chloride + Water + Carbon dioxide HCl(aq) + CaCO3(s) CaCl2(aq) + H2O(l) CO2 As you can see above, in the reaction, the reactants are hydrochloric acid and calcium...
