Question

Predict what is formed at each electrode in the electrolysis of:
1. molten lithium oxide

Answer 1

Ответ:

1. Electrolysis of the salt gives molten lithium metal, at the cathode due to the reduction of lithium ions.

2. At the same time, on the anode, chlorine gas is evolved due to the oxidation of chloride ions.

Answer 2

Ответ:The electrolysis of molten lithium oxide produces lithium metal at the cathode and oxygen gas at the anode. The reaction at the cathode can be represented as:

Li+ + e- -> Li (reduction)

The reaction at the anode can be represented as:

O2- -> 1/2 O2 + 2e- (oxidation)

As a result, lithium metal is deposited at the cathode and oxygen gas is evolved at the anode.
