    Answer: Aluminium oxide and zinc oxide are amphoteric oxides; they react with dilute hydrochloric acid to form corresponding chlorides and with aqueous sodium hydroxide to form soluble aluminates or zincates. Calcium oxide is a basic oxide; it reacts with dilute hydrochloric acid but not with sodium hydroxide. Sulphur dioxide is an acidic oxide; it does not react with hydrochloric acid but reacts with bases like sodium hydroxide to give sulphites/bisulphites, so statement IV is incorrect here.
