Calculate the standard reduction potenti...

Calculate the standard reduction potential of `Cd^(2+)//Cd` electrode for the cell :
`Zn(s)|Zn^(2+)("IM") || Cd^(2+)(IM)|Cd(s)`
`("Given that " E_(cell)^(@)=0.36 V and E_(Zn^(2+)//Zn)^(@)=-0.76V)`

Text Solution

Verified by Experts

`E_(cell)^(@)=E_(cathode)^(@)-E_(anode)^(@)`
`E_(cell)^(@)=(E_(Cd^(2+)//Cd)^(@))-(E_(Zn^(2+)//Zn)^(@))`
`(E_(Cd^(2+)//Cd))=E_(cell)^(@)+(E_(Zn^(2+)//Zn)^(@))=0.36+(-0.76)=-0.40 V`
