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

Explanation

The galvanic cell for the reaction is
`Zn(s)|Zn^(2+)(aq)|| 2Ag^(+)(aq) | 2Ag(s)`
(i) Zinc electrode (anode) is negatively charged.
(ii) From silver to zinc in external circuit
(iii) Anode :`" " Zn(s) to Zn^(2+)(aq) +2e^(-)`
Cathode : `2Ag^(+)(aq)+2e^(-) to 2Ag(s)`
