the reaction between calcium carbonate and hydrochloric acid AIM- My task is to investigate the reaction between calcium carbonate and hydrochloric acid, which produces calcium chloride, carbon dioxide, and water. To do this I will conduct an experiment. Word Equation: Calcium + Hydrochloric Calcium + Carbon Dioxide + Water Carbonate Acid Chloride Chemical Equation: CaCo3 (s) + 2Hcl (aq) CaCl2 + Co2 (g) + H20 (l) The key variables in this experiment that affect the rate of reaction is, surface area, temperature, mass of CaCo3 and concentration of acid. The surface area can be investigated by increasing or decreasing the surface area of the calcium carbonate (marble) chips (i.e. have them as chips or powdered). The temperature can be investigated by increasing the temperature of water in the water trough. Increasing or decreasing the mass of the calcium carbonate chips used in the experiment can investigate the mass. The concentration can be investigated by increasing or decreasing...
