Chapter 21, Problem 21.61QP

Interpretation Introduction

Interpretation:

How expect ${\text{H}}_{\text{2}}\text{O}$ and H to be reduced at the cathode and ${\text{H}}_{\text{2}}\text{O}$ oxidized at the anode has to be explained.

Concept introduction:

• The concept of electrolysis is based on redox process, so this process is must applied to the various metals and their separation process.
• By using electrolytic cells we can separate the pure metals.
• In electrolysis we must use anode and cathode.
