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")^(@) = + 0.46 V ` and `log 10^(n) = n`.

Text Solution

Verified by Experts

`Ag(s) |Ag^(+) ( 10^(-3) M ) | | Cu^(2+) ( 10^(-1) M ) | Cu (s) `
`E_("cell")^(@) = + 0.46 V ` and `log 10^(n) = n, T = 25^(@)C`
`E_("cell" ) = E_("cell")^(@) - ( 0.059)/( n ) log "" ([ Cu^(2+)])/([Ag^(+)]^(2))`
`= 0.46 - (0.059)/( n ) log ""(( 10^(-1)))/(( 10^(-3))^(2))`
`= 0.46 - ( 0.059)/( n ) log 10^(5) = 0.46 - ( 0.059)/( 2) xx ( 5)`
`= 0.46 - 0.1475 = 0.3125V`
