Question

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

• A. With the iron spoon
• B. With the positive terminal
• C. With the negative terminal
• D. Between the positive and negative terminal of battery.

Answer 1

The correct option is B With the positive terminal

In order to deposit the copper on the iron spoon, $C{u}^{2+}$ present in the solution should deposit to iron spoon and we know that $C{u}^{2+}$ will move toward negative terminal as it is positively charged. So the iron spoon is to be connected with negative terminal and $Copper$ plate is to be connected with $positive$ terminal.

Therefore, B is correct option.
