Answer: We have
The galvanic cell corresponding to the given redox reaction can be represented as:
Zn / Zn2+(aq) // Ag+(aq) / Ag
(i) Zn electrode is negatively charged because at this electrode, Zn oxidizes to Zn2+ and the leaving electrons accumulate on this electrode.
(ii) Ions are the carriers of current in the cell.
(iii) The reaction taking place at Zn electrode can be represented as:
Zn(s) → Zn2+ + 2e-
And the reaction taking place at Ag electrode can be represented as:
