# 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.

(i) $Zn$ electrode is negatively charged because it loses electrons (act as an anode)
(iii) At Anode-  $Zn\rightarrow Zn^{2+}+2e^{-}$
At Cathode $Ag^{+}+e^{-}\rightarrow Ag$
