Question

Can chlorine gas be stored in a copper cylinder? Given `E_(Cu^(2+),Cu)^(@)=0.34V and E_(Cl^(2),Cl^(-))^(@)=1.36V`

Answer 1

`Cu+Cl_(2)toCuCl_(2),i.e., Cu^(2+)+2Cl^(-)`
`E_(cell)^(@)=E_(Cu//Cu^(2+))^(@)+E_(Cl_(2)//2Cl^(-))^(@)=-0.34+1.36V=1.02V`.
i.e., reaction takes place. Hence, it cannot be stored.
