Question

(a) In which state Lead bromide conducts electricity?

Answer 1

Lead bromide will conduct electricity in a molten state.

Electrolysis of Molten Lead Bromide:

• Electrolysis of Lead bromide is carried out by taking solid Lead bromide and heating it in a silica crucible.
• Solid Lead bromide does not conduct electricity as its ions are held tightly. It is heated to ${380}^{\mathrm{o}}\mathrm{C}$ to melt and is kept molten by slow heating.

The reaction that occurs during electrolysis:

${\mathrm{PbBr}}_2\rightleftharpoons {\mathrm{Pb}}^{2+}+2{\mathrm{Br}}^{-}$

Hence, Lead bromide will conduct electricity, when it is in a molten state.
