Topic 9 Reactions of Acids
Limewater Acid Metal Carbonate Acids and Metal Carbonates Experiment Aim: To investigate the reaction between metal carbonate and acids. Method:
Results: Conclusion: Carbonates react with acids to produce CO2(g) which is an acidic gas.
Acids and Metal Carbonates • Carbonate rocks are used in a lot of buildings. When acid rain falls on these buildings the acid reacts with the carbonate in a neutralisation reaction. Metal Carbonate +Acid Salt+Water+Carbon dioxide Calcium carbonate Calcium chloride+ +Hydrochloric acid water+carbon dioxide CaCO3 + HCl CaCl2 + H2O + CO2
Examples Calcium carbonate Calcium nitrate + water + Nitric acid + carbon dioxide CaCO3 + 2HNO3 Ca(NO3)2 + H2O + CO2
Magnesium carbonate+ Magnesium chloride hydrochloric acid + water +carbon dioxide MgCO3 + HCl MgCl2 + H2O + CO2 In these reactions the H+ of the acid reacts with the CO3- ions of the metal carbonate to form water and carbon dioxide. The H+ ion is replaced by the metal ion: Neutralisation reaction.
