• The oxides of a metal are basic in nature or in other words they react with acids to form salt and water. In the case of non-metals, they are acidic in nature to form acids when they dissolve in water. Sulphur-dioxide dissolved in water can be tested with litmus.

SO 2 +2H 2 O→H2 SO4+2H.

• Sulphuric acid is acid that turns blue litmus to red.
