Question

Compose the cathode and anode processes of electrolysis of an aqueous solution Li2SO4, the total electrolysis equation

Answer 1

Step-by-step explanation:

The electrolysis of an aqueous solution of Li2SO4 involves the following processes:

At the cathode:

2H2O + 2e- → H2 (g) + 2OH-

At the anode:

2OH- → 1/2O2 (g) + H2O + 2e-

The overall reaction for the electrolysis of Li2SO4 is:

2Li2SO4 (aq) + 2H2O (l) → 2LiOH (aq) + H2 (g) + SO2 (g) + 1/2O2 (g)

Note: The reaction also produces SO2 gas in addition to H2 and O2.
