The galvanic cell in which the given reaction takes place is depicted as: Zn(s) | Zn2+ (aq) || Ag+ (aq) | Ag(s)
(i) Zn electrode (anode) is negatively charged
(ii) Tons are carriers of current in the cell and in the external circuit, current from silver to Zinc.
(iii) The reaction taking place at the anode is given by, Zn(s) - H → Zn2+(aq) + 2e-
The reaction taking place at the cathode is given Ag++ e- → Ag(s)
