Give four method of acid preparation and give two reactions to support your answer

Synthetic method : In the synthetic method, acids are prepared by direct combination of elements. For example, hydrogen and chlorine react together under the action of an electric spark to produce hydrogen chloride gas which is absorbed in water to give hydrochloric acid. Nitric acid reacts with sodium carbonate to form sodium nitrate, carbon dioxide and water. Sulfuric acid reacts with calcium carbonate to form calcium sulfate, carbon dioxide and water. Hydrochloric acid reacts with calcium carbonate to form calcium chloride, carbon dioxide and water.
