Question

What are the checmical reactions that occur in nelson cell

Answer 1

Answer:

The reactions areAt anode:At cathode:(from water) It may be noted here that it is H+(aq) and not Na+(aq) which is involved in the electrode reaction (reduction) at the cathode. The presence of free Na+(aq) and OH−(aq) in the solution thus yields NaOH solution. Hydrogen gas is obtained as a by–product at the cathode
