Investigate the factors, which affects how quickly Calcium carbonate reacts with hydrochloric acid. Rate of Reactions Aim The aim of this experiment is to find out how different variables affect the rate at which the reaction between Marble chips (CaCO3) and Hydrochloric acid (HCl) takes place. There are many variables that affect the rate of this reaction such as the following: 1. Temperature 2. Concentration 3. Surface area In my investigation I will be testing how changing the concentration of the Hydrochloric acid, the surface area of the marble chips and the temperature have an effect on 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 CaCO3 + 2HCL = CaCl2 + H2O +CO2 Hydrochloric acid + Calcium Carbonate =Calcium Chloride + Water + Carbon dioxide Prediction My plan is to investigate three factors that could affect the rates of reaction. These factors are -...
