In this investigation I am planning to look at the effect of concentration on rate of reaction. The reaction I am going to use is calcium carbonate (chalk or marble chips) reacting with different concentration of hydrochloric acid. The following are the equations for the reaction: Calcium Carbonate + Hydrochloric Acid Calcium Chloride + Water + Carbon Dioxide CaCO3 (s) + 2HCl (aq) CaCl2 (aq) + H2O (l) + CO2 (g) As I am only looking at the effect of concentration has on the rate of reaction, other factors (i.e. temperature and surface area) which will affect the rate of reaction must not vary for it to be a fair test. The rate of reaction is calculated by measuring the mass loss due to carbon dioxide given off during the reaction. I choose to use calcium carbonate because it is not a very reactive compound so the rate of carbon dioxide produced will...
