Explanation:When non-metals are dissolved in water they produce acidic oxides.And most metals, give rise to basic oxides.The formation of H+ (aq) ions in solution causes a substance's acidic nature.The formation of OH‚¬€œ (aq) ions in solution are responsible for a substance's basic nature.Non-metals do not react with water but the non-metal oxides do react with water and they produce acids.Non-metallic oxide dissolves in water to form an acid.CO2 + H2O ? H2CO3Carbonic acid (H2CO3) is an acid formed by the reaction of water (H2O) with carbon oxide (CO2).
