can chlorine gas be stored in copper cylinder ? given electrode potential for(Cu2+/Cu)= 0.34V and electode potential for (Cl2/Cl-)=1.36V


Eocell = Ecathode - Eanode.
Oxidation occurs at anode while reduction at cathode.
So,  Eocell = EoCu2+/Cu  - EoCl2/Cl-
Eocell  = 0.34 -(1.36)
Eocell = -1.02 V
As Eocell  is negative, therefore reaction is non- spontaneous, that is, reaction will  not occur. So we can place Cl2 gas in Cu cylinder.
