To investigate the effects of change of concentration on rate of reaction - between Calcium Carbonate and Hydrochoric Acid Planning Aim: To accurately investigate the affect of concentration of acid on the rate of reaction between Hydrochloric Acid and Calcium Carbonate. Theory Carbonates are compounds made of a metal cation and a carbonate anion. Calcium carbonate is an example of a carbonate. All carbonates react with acids to give off carbon dioxide. Calcium Carbonate (CaCo3) is a white, insoluble solid that occurs naturally as limestone, chalk, marble and calcite. In the case of this investigation the reaction between dilute Hydrochloric Acid and dry Calcium Carbonate the formula equation is: CaCO3(s) + 2HCl (aq) CaCl3 (aq) + CO2 (g) + H2O (l) The Rate of Chemical Reaction can be defined as "the time it takes for an amount of product to appear or for an amount of reactant to disappear." In this reaction we will be studying...
