Molten lithium bromide is electrolysed in an industrial process to produce lithium metal.

Draw on this

Which is the correct half-equation for the production of lithium?

Select one:

• $Li+e^{-}\to {Li}^{+}$
• $Li\to {Li}^{+}+e^{-}$
• ${Li}^{+}+e^{-}\to Li$
• ${Li}^{+}\to Li+e^{-}$

A porous mesh separator is used to keep the products of the electrolysis apart.

Suggest one reason why the products of the electrolysis must be kept apart.

Which type of particle passes through the mesh in the electrolysis of molten lithium bromide?

Choose from: Atom, Electron, Ion, Molecule.

Aqueous lithium bromide solution is electrolysed in a different industrial process. Two gases and an alkaline solution are produced.

Which two ions are present in aqueous lithium bromide solution in addition to lithium ions and bromide ions?

Name the alkaline solution produced.

Explain how the alkaline solution is produced. You should refer to the processes at both electrodes in your explanation.
