Derive Nernst equation for the cell.
`Ni(s)|Ni^(2+) (aq. 0.1 M)||Ag^(+) (aq. 0.1 M)|Ag (s)` and also find its cell potential. Given :
`E_(Ag^(+)//Ag)^(@)=0.80` volt and `E_(Ni^(2+)//Ni)^(@)=-0.25` volt

Text Solution

Verified by Experts

Cell reaction,
`Ni+2Ag^(+) rarr 2Ag+Ni^(2+)," "E_(cell)^(@)=1.05` volt
Nernst equation, `E_(cell)=E_(cell)^(@)-0.0591/2 "log "([Ni^(2+)])/([Ag^(+)]^(2))`
`=(1.05-0.0295)` volt
`=1.02` volt
