Hydrochloric acid and calcium carbonate Coursework HCl + calcium carbonate ? calcium chloride + carbon dioxide + water. HCl(aq) + CaCO3(s) CaCl2(aq) + CO2(g) + H2O(l) Aim The aim is to investigate the effect that increasing or decreasing the concentration of the HCL has on the speed of reaction, between HCl + CaCO3. We will determine the speed/ rate of reaction by measuring the amount of CO2 given off in a set time. Equipment * Tub of water * 2 measuring cylinders * 3 test tubes * Test tube rack * Top pan balance * Stand + clamp * Spatula * Piece of card * Delivery tube Method First I will prepare the experiment by collecting all of the necessary equipment and preparing it. Then I will measure out the correct amounts of HCL and CaCO3(s) using a measuring cylinder for the HCL and the scales to measure the CaCO3(s) . These will be 20ml of HCL and 50g of CaCO3(s). Ounce I...
