1.	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 ion will move towards anodeB. The positive and negative ion will move towards anode, the the negative ions will stop movingC. the negative ions will continut to move towarsa anode while positive ions will stop movingD. the positive and negative ions will start moving randomly
Answer» Correct Answer - D In the absence of electric feld the ions in the solution move radomly due to thermal energy.
