Solution

The correct option is B Smaller amount of copper will be deposited on the plate connected to the negative electrode.
Larger the distance between the electrodes, greater is the internal resistance which offers more obstruction to the flow of current. Hence smaller amount of copper will be deposited at the cathode.

Q. Question 19
In the circuit given as 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 the negative electrode. Will copper be still deposited on the carbon rod? Explain your answer.

Q. During copper plating, ions from the electrolyte are drawn to the negative electrode and are deposited on it.

If you pass current through copper sulphate solution, copper gets deposited on the plate connected to the positive terminal of the battery.

Q. To deposit the copper on the iron spoon, the copper plate is to be connected:

Assertion: Upal observed that copper is deposited on the negative electrode connected to the terminal of the battery. Kavya performed the same experiment but she replaced the copper electrode with a carbon electrode and still observed copper is deposited over carbon rod.

Reason: Copper sulphate solution dissociates into copper and sulphate ions when electricity is passed through dilute copper sulphate solution and this free copper ions deposit on the carbon rod.
