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 set-up will be similar to that. The cell will be represented as:
`Zn(s)|Zn^(2+)(aq)||Ag^(+)(aq)|Ag(s)`
(i) Anode, i.e.,z inc electrode will be negatively charged.
(ii) The current will flow from silver to copper in the external circuit.
(iii) At anode: `Zn(s)toZn^(2+)(aq)+2e^(-)`
At cathode: `Ag^(+)(aq)+etoAg`
