(a)What is the nature of the oxide SO2? What happens when it is dissolved in water? Write the chemical equation of the reaction involved.
(b)What is the nature of the oxide Na2O? What happens when it is dissolved in water? Write the chemical equation of the reaction involved.
(a) SO2 is acidic in nature as it turns blue litmus red. It produces sulphurous acid when dissolved in water.
The equation for the reaction is given as:
$SO_2(g) + H_2O(l) → H_2SO_3 (aq)$
(b) Na2O is basic in nature as it turns red litmus blue. It produces an alkali called sodium hydroxide when dissolved in water.
The equation for the reaction is given as:
$Na_2O + H_2O → 2NaOH$
