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.

Answer»

Solution :`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)`
