Following reactions are taking place in a Galvanic cell , `Zn to Zn^(2+) + 2e^(-) , Ag^(+) + e^(-) to Ag`
Which of the given representations is the correct method of depicting the cell ?

Options

A. `Zn_((s)) | Zn_((aq))^(2+)"||"Ag_((aq))^+ | Ag_((s))`
B. `Zn^(2+)| Zn||Ag|Ag^+`
C. `Zn_((aq))|Zn_((s))^(2+) "||"Ag_((s))^+ | Ag_((aq))`
D. `Zn_((s)) | Ag_((aq))^+ "||" Zn_((aq))^(2+) | Ag_((s))`

Answer

A

Explanation

`Zn+2Ag^(+) to Zn^(2+) + 2Ag ` can be represented as `Zn_((s))|Zn_((aq))^(2+)||Ag_((aq))^+ |Ag_((s))`
