• # question_answer 40) Depict the galvanic cell in which $Zn(s)+2A{{g}^{+}}\to Z{{n}^{2+}}(aq)+2Ag(s)$takes place. Further show: (i) Which electrode is negatively charged? (ii) Carriers of current in the cell. (iii) Individual reaction at each electrode.

(i) $\underset{Anode}{\mathop{Zn(s)|Z{{n}^{2+}}}}\,||\underset{Cathode}{\mathop{A{{g}^{+}}|Ag(s)}}\,$ Oxidation takes place at anode and reduction at cathode. (ii) Electrons (iii) $Zn(s)\to Z{{n}^{2+}}+2{{e}^{-}}$(Anode) $C{{u}^{2+}}+2e\to Cu(s)$ (Cathode)
