Answer»

Solution :(i) Anode : Zinc CONTAINER
(ii) Cathode : Graphite ROD in contact with `MnO_(2)`
(iii) Electrolyte : Ammonium chloride and zinc chloride in water
(iv) Oxidation at anode :
`""Zn_((s)) rarr Zn_((AQ))^(2+)+2E^(-)`
(v) Reduction at cathode :
`""2NH_(4(aq))^(+)+2e^(-) rarr 2NH_(3(aq))+H_(2(g))`
