8.30 Depict the galvanic cell in which the reaction 

Zn(s)+2Ag^{+}\rightarrow Zn^{2+}(aq)+2Ag(s)
takes place, Further show:

(i) which of the electrode is negatively charged,

(ii) the carriers of the current in the cell, and

(iii) individual reaction at each electrode.

Answers-

(i) Zn electrode is negatively charged because it loses electrons (act as an anode)

(ii) electron flow from negatively charged electrode to a positively charged electrode (anode to cathode) and the flow of current is just reversed. So current flow through silver cathode to the zinc anode.

(iii) At Anode-  Zn\rightarrow Zn^{2+}+2e^{-}

   At Cathode Ag^{+}+e^{-}\rightarrow Ag
