Question

Depict the galvanic cell in which the reaction, Zn(s)+2Ag+(aq)Zn2+(aq)+2Ag(s) takes place . Further show :

Which of the electrode is negatively charged

The carriers of the current in the cell

Individual reaction at each electrode

Open in App
Solution

(a). The galvanic cell for the reaction is represented as

Zb(s)|Zn2+(aq)||2Ag+(aq)|2Ag(s)

Zinc electrode (anode) is negatively charged.

(b). Electrons and ions are carriers of current in the cell and in the external circuit, current will flow from silver to zinc.

(c). The individual reaction at each electrode

Anode: Zn(s) Oxidation−−−−− Zn2+(aq) + 2eCathode: 2 Ag+(aq) + 2e Reduction−−−−− 2 Ag(s)
