MCQ
The electric current in a chemical cell is due to movement of:
- APositive hole charges.
- BPositive ions only.
- CNegative ions only.
- ✓Positive and negative ions.
✓
Answer
Correct option: D.
Positive and negative ions.
An electrolyte solution is formed by mixing an electrolyte in a solvent. The electrolyte on dissolution furnishes ions. The preferred movement of ions under the influence of the electric field is responsible for electric current. Hence, the electric current in a chemical cell is due to the movement of positive and negative ions.
