Lead bromide must be molten for electrolysis to occur because in the molten state, the ions are free to move and conduct electricity. This allows for the dissociation of lead bromide into its ions, which can then be attracted to the electrodes for the electrolysis process. In the solid state, the ions are not mobile and cannot participate in the electrolysis reaction.

Why does electrolysis not occur unless lead II bromide is molten?
Electrolysis requires the movement of ions to conduct electricity. In solid lead II bromide, the ions are held in fixed positions and cannot move freely to carry an electric current. When lead II bromide is molten, the ions are free to move and can participate in electrolysis.
Why must lead bromide must be molten for electrolysis to take place?
Lead bromide must be molten for electrolysis to take place because in its solid state, the lead and bromide ions are not free to move and carry an electric charge. In a molten state, the ions are free to migrate to the electrodes and participate in the electrolysis process, allowing electric current to pass through the molten lead bromide solution.
How could lead bromide be made into a liquid for electrolysis?
Lead bromide can be dissolved in a suitable solvent, such as water or an organic solvent, to form a liquid electrolyte solution for electrolysis. Heating the solvent can help in dissolving the lead bromide more efficiently. Ensure that the concentration of lead bromide in the solution is appropriate for the electrolysis process.
Which elements would you get when electricity is passed through molten lead bromide?
When electricity is passed through molten lead bromide, the lead bromide will undergo electrolysis. This process will result in the decomposition of the lead bromide into its constituent elements, which are lead and bromine. Lead will be deposited at the cathode, while bromine gas will be produced at the anode.
What particles are present in molten lead ii bromide?
In molten lead(II) bromide, the particles present are lead(II) ions (Pb^2+) and bromide ions (Br^-), as the solid compound dissociates into its constituent ions in the molten state due to the high temperature. These ions are responsible for the electrical conductivity and other properties observed in the molten state.

What is produced at the positive electrode of the electrolysis of molten lead bromide?
At the positive electrode (anode) of the electrolysis of molten lead bromide, bromine gas is produced. This is because bromine ions are attracted to the positive electrode, where they are oxidized to form bromine gas.

Molten sodium iodide?
cell emf for electrolysis of molten lead (II) iodide
Why can molten lead bromide conduct electricity?
Molten lead bromide can conduct electricity because the ions in the molten state are free to move and carry electric charge. When an electric field is applied, the positive lead ions and negative bromide ions are attracted towards oppositely charged electrodes, allowing for the flow of current.
How do you make lead from lead 2 bromide?
Lead can be obtained from lead (II) bromide through a process called electrolysis. When lead (II) bromide is melted and electrolyzed, the lead ions migrate to the negative electrode (cathode) and are reduced to form lead metal, while bromide ions move to the positive electrode (anode) and are oxidized to produce bromine gas. This allows for the isolation of lead from lead (II) bromide.
What happens during the electrolysis of molten lead iodide?
During the electrolysis of molten lead iodide, lead ions (Pb2+) are reduced at the cathode to form molten lead metal, while iodide ions (I-) are oxidized at the anode to form iodine gas and release electrons. This process helps separate the elements in the compound by using electrical energy.
What are three substances that can undergo electrolysis?
distilied water, sodium chloride, lead bromide and cooper sulfate.
