Depict the galvanic in whiCHM the reaction `:`
`Zn(s)+2Ag^(o+)(aq) rarr Zn^(2+)(aq)+2Ag(s)` takes place.
Further show `:`
` a.` WhiCHM of the electrode is negatively CHMarged ?
`b.` The carriers of the current in the cell.
`c.` Individual reaction at eaCHM 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))`
