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 surface area makes an effect and changes the speed of the reaction. The reaction that will take place is: Hydrochloric acid + Calcium Carbonate Calcium Chloride + Water + Carbon dioxide Prediction The more surface area there is the faster the reaction will take place, because there is a larger surface area for the acid to react with. More collisions between the two reactants (HCl and CaCO) will take place resulting in a quicker time for the reaction. If the temperature at which the reaction takes place is...
