Depict the galvanic cell in which the reaction
`Zn(s)+2Ag^(+)(aq)toZn^(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.
(iii). Individual reaction at each electrode.

Explanation

`Zn(s)|Zn^(2+)(aq)||Ag^(+)(aq)|Ag(s)`
(i) `Zn//Zn^(2+)` electrode is negatively charged.
(ii) Carriers of current in the outer circuit are electrons which flow from Zn electrode to silver electrode.
At anode : `Zn(s)toZn^(2+)(aq)+2e^(-)`
At cathode : `2Ag^(+)(aq)+2e^(-)to2Ag(s)`
