Sodium reacts with dihydrogen to form a crystalline ionic solid. It is non-volatile and a non-conductor of electricity. It also reacts vigorously with water to liberate `H_(2)` gas. Write the formula of the ionic solid and give reaction between this solid & water. What happens when the ionic solid in its molten state is electrolysed?
