In the circuit given in the figure, Boojho observed that copper is deposited on the electrode connected to the negative terminal of the battery. Paheli tried to repeat the same experiment. But she could find only one copper plate. Therefore, she took a carbon rod as negative electrode. Will copper be still deposited on the carbon rod? Explain your answer.

Yes, If Paheli uses a Carbon rod as an electrode connected to the negative terminal of the battery, then copper sulphate solution dissociates into copper and sulphate ions on passing the current. The free copper ions start getting drawn to the carbon rod as it is connected to the negative terminal of the battery. Thus, she will find the carbon rod coated with copper.
