Question

Which of the following compounds is a good
conductor of electricity in solution state?
(a) Covalent
(b) Molecular solid
(c) Metallic solid
(d) Ionic compounds

Answer 1

ionic compound is the answer

Answer 2

(d) Ionic compounds

Explanation:

Ionic compounds in the solid state are not good conductors of electricity as they are strongly bonded and the ions are not able to move to conduct electricity.

However, in the liquid state, i.e. the solution state, they dissociate into their respective ions and are hence free to move. So they are good conductors of electricity.

Option D is the answer.
