Question

A half cell reaction is one which:

• A. involves only half a mole of electrolyte
• B. goes only half way to completion
• C. takes place at one electrode
• D. consumes half a unit of electricity

Answer 1

The correct option is C takes place at one electrode

In an electrochemical cell, a redox reaction occurs. Oxidation occurs at one electrode and reduction occurs at another electrode. The reaction occuring at each electrode is known as half cell reaction.

Hence, option C is the correct one.
