An Experiment to show the reaction between Hydrochloric acid and Calcium Carbonate Introduction Hydrochloric acid + Calcium Carbonate ? Calcium Chloride + Carbon Dioxide + Water 2HCl(aq) + CaCO3(s) ? CaCl2(aq) + CO2(g) + H20(l) In this experiment we will be investigating the variables that can affect the speed of reaction between hydrochloric acid and calcium carbonate. During this experiment carbon dioxide is produced. This is what we are going to use to record the speed of reaction, for the faster the reaction the faster carbon dioxide is produced. Variables A variable affects the rate of reaction between a number of chemicals. For a reaction to occur the particles have to collide with sufficient energy to break the bonds between them. This amount of energy needed is called Activation energy. In a reaction, only the particles with energies above the Activation Energy will cause a reaction. The different variables that could be used are: ? the surface...
