Lead(II) bromide is used because it melts at an unusually low temperature for an ionic compound (373 °C). Lead can be fairly safely handled afterwards (taking care to ensure that hands are washed after any contact with the metal). Bromine is a coloured acidic gas with a characteristic smell.

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.

At the cathode (-) molten lead is formed:

Pb2+(l) + 2e- → Pb(l)

At the anode, gaseous bromine is evolved:

2Br-(l) → Br2(g) + 2e-

Does calcium bromide conduct electricity?

Yes, calcium bromide in its solid form does not conduct electricity because it is made up of a lattice structure of ions that are held together by strong ionic bonds. However, when dissolved in water or melted, calcium bromide will dissociate into ions and can conduct electricity as ions are free to move and carry an electric current.


Does sodium bromide conduct electricity?

Sodium bromide is an ionic substance. It conducts electricity when melted or when dissolved in water. This is due to the sodium, Na+ ions and the Br- ions present. It does not conduct electricity in the solid state as the ions can not move.


Does solid potassium bromide conduct electricity?

No because it's a crystalline ionic solid. However, dissolve some KBr in water and it will conduct electricity nicely, because in solution it's an electrolyte, with lots of little K+ and Br- ions floating around.


Does aluminum bromide conduct electricity?

Aluminum bromide is an ionic compound and therefore does not conduct electricity in its solid state because the ions are not free to move. However, when molten or dissolved in water, it can conduct electricity due to the mobility of the ions.


Under what conditions can potassium bromide cunduct electricity?

Potassium bromide can conduct electricity when dissolved in water or melted, as it forms ions that are free to move and carry an electric charge. In its solid form, potassium bromide is not a good conductor of electricity because the ions are not free to move.

Does solid lead bromide conduct electricity?

No, solid lead bromide does not conduct electricity because it is an ionic compound with fixed ions that are not free to move and carry electric charge. Only when lead bromide is melted or dissolved in water to form an electrolyte solution, the ions become free to move and conduct electricity.


Does sodium bromide conduct electricity when sold?

Yes, sodium bromide conducts electricity when dissolved in water. In its solid state, sodium bromide does not conduct electricity because the ions are not free to move. However, when it is dissolved in water, it dissociates into sodium and bromide ions which are able to carry an electrical current.


Is bromide a non metal and a good conductor of electricity?

Bromine, as the element is called on its own is a nonmetal, and is a poor conductor of electricity. Bromide salts conduct electricity if dissolved in water or molten, but not in their normal solid states.

Is sodium bromide a conductor?

molten or in solution YES - in its natural form - no


Why can't potassium bromide be electrolysed when solid?

Potassium bromide cannot be electrolyzed when in solid form because the ions are not free to move in a solid crystal lattice structure. In order for electrolysis to occur, ions must be able to move freely in a liquid state to carry an electric current. When in a solid state, the ions are held in place and cannot conduct electricity.


Is sodium bromide a solid?

Yes, sodium bromide is a solid at room temperature. It is a white crystalline powder that is commonly used as a source of bromide ions in various chemical applications.


What is the phase of aluminum bromide at STP?

At standard temperature and pressure (STP), aluminum bromide exists as a solid.
