Aim: To investigate how concentration affects the rate of reaction we will be reacting Calcium Carbonate (CaCO3) and Hydrochloric Acid (HCl). To make this a fair test we will have to keep all variables the same except the one we are investigating. The products of the reaction between calcium carbonate and hydrochloric acid are calcium chloride and carbon dioxide. To measure the rate of reaction we will be measuring the volume of carbon dioxide produced. The size of the marble chips will be of a medium size, which we will keep the same throughout the experiment. The highest concentration of HCl subjected to the CaCO3 in the experiment is 2 molar. Prediction: I predict that the higher the concentration is the faster the reaction will take place this is because in a higher concentration there will more hydrochloric acid molecules per set volume. I will be using 0.1, 0.5, 1.0, 1.5...
