A current of 1 ampere is paased for one hour between nickel electrodes in 0.5 L of 2 M Ni (NO_(3))_(2) solution. What will be the molarity of the solution at the end of the electrolysis? |

Answer» SOLUTION :The CHANGES taking PLACE at the electrodes in the ELECTROLYSIS of `Ni(NO_(3))_(2)` solution using nickel electrodes will be as follows: At cathode: `Ni^(2+)+2etoNi` At anode: `NitoNi^(2+)+2e^(-)` thus, amount of nickel deposited on the cathode from the solution=nickel dissolved from the anode. Hence, molarity of the solution will REMAIN unchanged at the end of the electrolysis. |
