How does the concentration of acid affect the rate of a reaction with calcium carbonate? Calcium + Hydrochloric => Calcium + Carbon + Water Carbonate Acid Chloride Dioxide CaCO3 (s) + 2HCl (aq) => CaCl2 (aq) + CO2 (g) + H2O (l) Introduction I will be using the reaction between calcium carbonate and hydrochloric acid to see how the concentration of acid affects the rate of a reaction. By doing the above experiment I will prove that the higher the concentration of acid, the faster a reaction will occur. I have carried out a previous experiment called the 'Disappearing Cross', in which I used the reaction between thiosulphate, hydrochloric acid and water to see how concentration affects the rate of reaction. When we added the hydrochloric acid to the water and thiosulphate a reaction occurred, causing the water to become foggy so that the cross was no longer visible through the conical flask. The...
