On passing `H_2S` through an aqueous solution of `SO_2`, a yellow turbidity is formed. Why ?

Why does an aqueous solution of an acid conduct electricity?

why aqueous solution of acids conduct electricity?

Explain why an aqueous solution of CuSO_4 is acidic in nature ?

When electricity is passed through an aqueous solution of sodium chloride, three products are obtained. Why is it’s the process called chlor alkali?

In qualitative analysis when H_2S is passed through an aqueous solution of salt acidified with dil. HCl, a black precipitate is obtained. On boiling the precipitate with dil. HNO_3 , it forms a solution of blue colour. Addition of excess of aqueous solution of ammonia to this solution gives _______ .

when an aqueous solution of H_2SO_4 is electrolysed the product at anodes is :

Arsenous sulphide sol is prepared by passing H_(2) through arsenous oxide solution . The charge developed on the particles is due to adsorption of :

When SO_3 is bubbled through a solution of H_2SO_4 , a compound X is formed which further reacts with water to give H_2SO_4 . Explain the reaction.
