Question

Solid lead bromide does not conduct electricity. Why?​

Answer 1

Electrolysis is not possible with solid lead(II) bromide. This is because the ions are held in a three-dimensional lattice, unable to move freely to the electrodes. Melting enables the ions to become mobile and to travel to the respective electrodes.

Answer 2

Solid lead bromide does not conduct electricity due to the lack of free electrons, the non-metallic character, insulating properties of the crystal lattice, high resistance and the lack of mobility of ions.

• Lack of free electrons: Solid lead bromide is a compound that consists of positively charged lead ions (Pb2+) and negatively charged bromide ions (Br-). It contains no free electrons that can move through the crystal lattice and carry an electric charge.

• Non-metallic nature: Lead bromide is a non-metallic compound that does not have the characteristic properties of metals, including the ability to conduct electricity.

• Insulating properties: The crystal lattice of lead bromide is held together by strong ionic bonds that do not allow the free movement of electrons. As a result, it is an insulator and does not conduct electricity.

• High resistance: The absence of free electrons and the strong ionic bonds make it difficult for electricity to pass through the solid lead bromide. Hence, it has a very high resistance to electrical conductivity.

• Lack of mobility: The lead and bromide ions are held in fixed positions within the crystal lattice, which limits their mobility and makes it impossible for them to conduct electricity.
