SURFACE AREA AND RATES OF REACTION BETWEEN MABLE CHIPS AND HYDROCHLORIC ACID Aim In this experiment I have the choice to change the concentration of the hydrochloric acid or the size of marble chips. I have chosen to change the size of marble chips to investigate the rate at which the reaction will take place and to determine the size of marble chips that liberate the most and the least carbon dioxide gas. The word equation for the reaction between marble chips (also known as calcium carbonate chips) and hydrochloric acid Calcium carbonate + hydrochloric acid calcium chloride + water +carbon dioxide The chemical equation for the reaction between marble chips (also known as calcium carbonate chips) and hydrochloric acid CaCO3(s) + 2HCl(aq) CaCl2 (aq) + H20 (l) + CO2 (g) Fair test In order to keep a fair test, only the surface area (i.e. size) of the marbled chips is variable. Other variables...
