Expert Answer:

The galvanic cell in which the given reaction takes place is depicted as:

(i) Zn electrode act as anode in galvanic cell so it will be negatively charged.

 (ii) Electrons move anode to cathode in the external circuit, and the direction of flow of current is always opposite to the flow of electron so that current will flow from silver (cathode) to zinc (anode).


At anode

Zn(s) →  Zn2+(aq) + 2e

At cathode

Ag+ + e   →  Ag(s)
