The oxides of Na and Mg which show purely ionic bonding produce alkaline solutions with water as their oxide ions (O 2-) become hydroxide ions (OH-):; O 2- (aq) + H 2 O (l) → 2OH - (aq). The oxides of P and S which show purely covalent bonding produce acidic solutions with water because when these oxides react with water, they form an acid …

Nonmetal oxides dissolve in water to form acids. CO 2 dissolves in water to give carbonic acid, SO 3 gives sulfuric acid, and P 4 O 10 reacts with water to give phosphoric acid. Metal oxides, on the other hand, are bases. Metal oxides formally contain the O 2-ion, which reacts with water to give a pair of OH-ions. Metal oxides therefore fit the ...
