Hydrochloric acid and Marble Chips Aim The aim of this experiment is to find out how different variables affect the rate at which the reaction between Marble chips (CaCO ) and Hydrochloric acid (HCl) takes place. There are many variables that effect the rate of this reaction such as the following: 1. Temperature 2. Concentration (Pressure for gases) 3. Catalyst 4. Surface area In my investigation I will be testing how changing the concentration of the Hydrochloric acid makes an effect and changes the speed of the reaction. I will do various experiments and then evaluate the results and come to a conclusion. The reaction that will take place is Hydrochloric acid + Calcium Carbonate Calcium Chloride + Water + Carbon dioxide Hypothesis The more concentrated the acid then the quicker the reaction will take place, because there will be more HCl particles than water particles for the marble chips...
