An investigation to find out how the concentration of acid affects the rate of reaction between hydrochloric acid and calcium carbonate (magnesium ribbon) Planning The aim of my investigation is to find out how changing the concentration of acid affects the rate of the reaction between CaCO3 and HCl. To make my experiments fair tests, I will only change one variable: the concentration of the acid. I will have to keep the volume of the acid, the mass and size of the marble chips and the temperature of the acid the same in all my experiments to insure a fair test, because by changing any of the above I will change the conditions and therefore the results will be inaccurate and the rate of reaction will be affected. The products of the reaction between the hydrochloric acid and the magnesium ribbon are calcium chloride, water and carbon dioxide. CaCO3 (s) + 2HCl(aq) CaCl2 (l) +...
