Question

Lead bromide conducts electricity only in :

• A. molten state
• B. solid state
• C. gaseous state
• D. none of the above

Answer 1

The correct option is A molten state

Electrolysis of molten Lead bromide,
At anode:
$2B{r}^{-}\to B{r}_2$
At cathode:
$P{b}^{+2}+2e^{-}\to Pb$
Due to these ions and reactions, lead bromide conducts electricity.
