Chemistry Coursework to Investigate the Time Taken for a Reaction to Take Place Between Antacid Tablets and Hydrochloric Acid with a Varying Concentration. Background Chemistry The experiment consists of an antacid tablet reacting with hydrochloric acid. The chemical symbol for Hydrochloric acid is HCl. This means that it consists of hydrogen and chlorine. The part which reacts in the experiment is hydrogen. The antacid tablet consists of calcium carbonate, sucrose, maize starch, calcium searate, peppermint oil and saccharin sodium. The part which reacts in the antacid tablet is the calcium carbonate. The reaction between calcium carbonate and hydrochloric acid is as follows: Ca CO3 + 2HCl CO2 + H2O + CaCl2 Calcium carbonate + Hydrochloric acid Carbon dioxide + Water + Calcium Chloride The gas which I am collecting in a measuring cylinder will be carbon dioxide. The reaction will look like this: The hydrogen ions and the calcium carbonate ions must have a successful collision...
