Do all bases contain hydroxide ions?

A BASE is a metal oxide. A soluble base is an ALKALI and contains hydroxide ions. (-OH) Sodium oxide (Na2O) is a BASE Sodium hydroxide (NaOH) is an ALKALI. The alkali comes about because the sodium oxide dissolved in water to form the alkali. Na2O + H2O = 2NaOH .
