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 - Surface Area of calcium carbonate, Temperature of the water in the flask of hydrochloric acid is placed and the concentration of the hydrochloric
