MCQ
A half cell reaction is one which:
- AInvolves only half a mole of electrolyte.
- BGoes only half way to completion.
- CTakes place at one electrode.
- DConsumes half a unit of electricity.
Explanation:
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.
