They react with acids to form salt and water, and also react with bases to form salt and water. Zinc oxide (ZnO) is a common example of an amphoteric oxide. It reacts with an acid like HCl: ZnO + 2HCl \u2192 ZnCl\u2082 + H\u2082O, and it reacts with a base like NaOH: ZnO + 2NaOH + H\u2082O \u2192 Na\u2082[Zn(OH)\u2084] (sodium tetrahydroxozincate).<br \/>\n<\/section>\n<section id=\"pyq-key-points\">\nAmphoteric oxides can react with both acids and bases.<br \/>\n<\/section>\n<section id=\"pyq-additional-information\">\nCopper oxide (CuO), Magnesium oxide (MgO), and Calcium oxide (CaO) are typically basic oxides formed by metals. They react with acids but generally do not react with bases. For instance, MgO + 2HCl \u2192 MgCl\u2082 + H\u2082O, but MgO does not react with NaOH. Other examples of amphoteric oxides include Al\u2082O\u2083, PbO, SnO, etc.<br \/>\n<\/section>\n","protected":false},"excerpt":{"rendered":"<p>Which one of the following oxides shows both acidic and basic behaviour?
