Represent the cell in which the following reaction takes place `Mg(s)+2Ag^(+)(0.0001M)toMg^(2+)(0.130M)+2Ag(s)`
Calculate its `E_((cell))` if `E_((cell))^(Ө)=3.17V`

Text Solution

Verified by Experts

`E_("cell")` is written directly from `E_("cell")^(@)` as,
`E_("cell") = E_("cell")^(@) - (RT)/(2F) "ln" ([Mg^(2+)])/([Ag^+]^(2)) " (or) " E_("cell") = 3.17 - (0.059)/2 "log" (0.13)/((0.0001)^(2))`
`E_("cell")` of the given reaction = `3.17 - 0.21 = 2.96 V`.
