Question

The cell , `Zn | Zn^(2+) (1M) || Cu^(2+) (1M) Cu (E_("cell")^@ = 1. 10 V)`,
Was allowed to be completely discharfed at `298 K `. The relative concentration of `2+` to `Cu^(2+) [(Zn^(2=))/(Cu^(2+))]` is :
A. `9.65 xx 10^(4)`
B. antilog (24.08)
C. `37.3`
D. `10^(37.3)`

Answer 1

Correct Answer - D
`E = E^(@) - (0.059)/(2) log.([Zn^(2+)])/([Cu^(2+)])`
`0 = 1.10 - (0.059)/(2) log. ([Zn^(2+)])/([Cu^(2+)])`
`log .([Zn^(2+)])/([Cu^(2+)]) = 37.3 :. ([Zn^(2+)])/([Cu^(2+)]) = 10^(37.3)`
