Calculate the emf of the following cell ...

Calculate the emf of the following cell at `25^(@)C` Ag(s) |Ag+ (10^(-3)M) | |Cu 2+ (10^(-1)M | Cu(s) :
Given `E_("cell")^(@)=+0.46V and log10^(n)=n`.

Text Solution

Verified by Experts

`E_("cell")=E_("cell")^(@)-(0.059)/(n)log""([Ag^(+)]^(2))/([Cu^(2+)])=0.46(0.059)/(2)log""((10^(-3))^(2))/(10^(-1))`
`=0.46-(0.059)/(2)(-5)=0.46+0.295=0.755V`.
