MCQ
The half $-$ cell reaction is the one that :
- ✓Takes place at one electrode.
- BConsumes half a unit of electricity.
- CInvolves half a mole of electrolyte.
- DGoes half way to completion.
✓
Answer
Correct option: A.
Takes place at one electrode.
A half reaction is either the oxidation or reduction reaction component of a redox reaction. A half reaction is obtained by considering the change in oxidation states of individual substances involved in the redox reaction. Half $-$ reactions are often used as a method of balancing redox reactions.
