Aim: To Find out if the concentration of Hydrochloric acid effects its reaction time with calcium carbonate Hypothesis: The reaction I am going to be investigating is Calcium Carbonate + Hydrochloric Acid Calcium Chloride + Carbon Dioxide + Water CaCO3(S) + 2HCL(aq) CaCl2(AQ) + CO2(g) + H2O I predict that an increase in the concentration of Hydrochloric acid will result in an increase in the speed of the rate of reaction it has with Calcium Carbonate. I also think that when you double the concentration you will double the rate of reaction. I believe this because my Preliminary work shows that 2.0 molar is a fast reaction so this means that the bigger the concentration of Hydrochloric acid the quicker the reaction time will be. It also shows that when you double the concentration you double the rate of reaction, but that could just be coincidence. I think this because a reaction happens...
