Determine electromotive force of the given concentration cell at `25^(@)C`:
`Zn|ZnSO_(4)(0.05M)||ZnSO_(4)(0.5M)|Zn`

Text Solution

Verified by Experts

`{:("Anode reaction: "Zn" "rarr" "Zn^(2+)(0.05M)+2e),("Cathode reaction : "Zn^(2+)(0.05M)+2e" "rarr" "Zn),(bar(" Cell reaction: "Zn^(2+)(0.5M)" "rarr" "Zn^(2+)(0.05M)" ")):}`
`therefore" "E_("cell")=-(0.059)/(2)log.(0.05)/(0.5)=0.0295V" "[because E^(@)=0]`
