प्रश्न
Observe the circuit given in the figure.
Boojho set up this circuit for purification of copper. What will be the nature of – (a) plate A (b) plate B (c) and the solution.
Explain the process of purification.
उत्तर
Following steps can be taken for the purification of copper in the given circuit:
- Plate A made up of pure copper.
- Plate B made up of impure copper.
- Copper Sulphate as the solution.
When electricity is passed through the copper sulphate solution, it dissociates into copper and sulphate ions. These copper ions have positive charge, hence they get deposited on the negative terminal which is made up of pure copper. This process is known as electroplating.
