Question 1 :
Assertion:&#160;Dry cell is a primary&#160;cell and lead storage cell is a&#160;secondary&#160;cell.<br/>Reason: A primary cell can only be used once while secondary cells are rechargeable.<br/>

Question 3 :
When the electric current is passed through a cell having an electrolyte, the positive ions move towards cathode and negative ions towards the anode. If the cathode is pulled out of the solution then____________.
