`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 given redox reaction is
`Zn(s)+2Ag^(+)(aq)rarrrZn^(2+)(aq)+Ag(s)`
since Zn gets oxidised to `An^(2+)` ions and `Ag^(+)` gets reduced to Ag metal therefore oxidation occurs at the zinc electrode and reduction occurs at the silver electrode thus galvanic cell corresponding to the above redox reaction may be diepiceted as `Zn|Zn^(2+)(aq)||Ag^(+)(aq)|Ag`
(i) since oxidation occurs at the zinc electode therefore electrons accumulates on the zinc electode and hence zin electrode is negative charged
(ii) The ion carry current the electrons flow from to Ag electrode while the current flows from Ag to Zn electrode
(iii) The reaction occuring at the two electrode are
`Zn(s)rarrZn^(2+)(aq)+21E^(-)`
`Ag^(+)(aq)+e^(-)rarrAg(s)`
