When the electric current is passed through a cell having an electrolyte, the positive ions move towards cathode and negative ions toqards the anode. If the cathode is pulled out of the solution .

A

The positive and negative ions will move towards the anode

B

The positive ions will start moving towards the anode, the negative ions will stop moving

C

The negative ions will continue to move towards the anode and the positive ions will stop moving

D

The positive and negative ions will start moving randomly

Text Solution

Verified by Experts

The correct Answer is:
D

In the absence of electric field the ions in the solution move randomly due to thermal energy
