The symptoms of acidity are controlled by an antacid. Commercially availableantacids consist of magnesium hydroxide, sugar and flavouring agents. Thehydrochloric acid in the stomach is neutralised by the magnesium hydroxide to formsalt and water. The mass of salt and water formed is equal to combined mass of baseand acid reacted.17.
