The reaction between an acid
The reaction between an acid and a base to give a salt and water is called neutralisation. In ionic form, it is H+ plus OH- giving water.
Metal oxides react with acids
Metal oxides react with acids to give salt and water, so they are basic oxides. Non-metallic oxides react with bases and are acidic in nature.
