Chemistry Coursework Year 11 Planning Preliminary work I mixed hydrochloric acid and calcium carbonate. It produced water, calcium chloride and carbon dioxide. I am going to collect the carbon dioxide in my main experiment. The equation for the experiment is: hydrochloric acid + calcium carbonate water + calcium chloride + carbon dioxide Aim My aim is to investigate a method of altering the rate/speed of the reaction between hydrochloric acid and calcium carbonate (marble/chalk) Variables Particle size of calcium carbonate - with this I would only change the particle size. I am not going to do this one because there are only tree different sizes I could use so my results will be limited Concentration of hydrochloric acid - with this I would change the concentration of the hydrochloric acid. I am not going to do this because it will take to long. The variable which I am going to use is the temperature of the hydrochloric acid I am...
