1.	A current of `3.7A` is passed for `6h` between nickel electrodes in `0.5L` of a `2M` solution of `Ni(NO_(3))_(2)`. What will be the molarity of the solution at the end of electrolysis?
Answer» The electrolysis of `Ni(NO_(3))_(2)` in presence of `Ni` electrode will bring in following changes : At anode : `Ni rarr Ni^(2+)+2e` At cathode : `Ni^(2+)+2e rarr Ni` Eq. of `Ni^(2+)` formed = Eq. of `Ni^(2+)` lost Thus, there will be no change in conc. of `Ni(NO_(3))_(2)` sol. during electrolysis i.e., It will remain `2M`.
