1. Give the equations for the reactions of aluminium hydroxide, magnesium hydroxide and sodium hydrogencarbonate with hydrochloric acid.2. Two well known antacids go by the name of ‘Rennies’ and ‘Milk of magnesia’. Rennies are essentially calcium carbonate and Milk of magnesia is essentially magnesium hydroxide. If stomach acid has a pH of 2 calculate the mass of calcium carbonate required to neutralise 10 cm3...
