Depict the galvanic cell in which the reaction Zn(s) `+ 2 Ag^(+) (aq) to Zn^(2+) (aq) + 2 Ag(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.

Text Solution

Verified by Experts

The reaction is `Zn_((s)) + 2Ag _((aq))^(+)rightarrow Zn_((aq))^(+) + 23Ag_((s))`
Cell can be represented as `Zn| Zn_((aq))^(2+) ||Ag_((aq))^(+) |Ag`
(i) The zinc electrode is negatively charged (anode) as it pushes the electrons into the external circuit.
(ii) Ions are the current carries within the cell.
(iii) The reactions occurring at two electrodes are:
At zinc electrode (anode) : `Zn_((s)) rightarrow Zn_((aq))^(2+) + 2e^(-)`
At silver electrode (cathode): `Ag_((aq))^(+) + e^(-)rightarrow Ag_((s))`
