Question

(a) Why does an aqueous solution of hydrochloric acid conduct electricity?
(b) Will the bulb glow if glucose solution is taken in the beaker instead of hydrochloric acid?
Why?

Answer 1

Answer:

Explanation:

(a) Aq. HCl conducts electricity because HCl is an ionic solid, and in solution it dissociates into H⁺ and Cl⁻, the ions help to conduct electricity.

(b) The bulb will not glow if a solution of glucose is taken, because glucose is a covalent molecule and it doesn't dissociate into ions, so electricity is not conducted and the bulb doesn't glow.
