MCQ
When electric current is passed through a cell having an electrolyte, the positive ions move towards the cathode and the negative ions towards 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
  • ✓
    The positive and negative ions will start moving randomly
✓

Answer

Correct option: D.
The positive and negative ions will start moving randomly
d
(d)In the absence of electric field the ions in the solution move randomly due to thermal energy.
