Question

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

Answer 1

No, chlorine gas can't be stored in copper vessel since it will reduce Chlorine gas to Copper chloride.

Answer 2

Answer: Chlorine gas can not be stored in copper cylinder.

Explanation:

In order to determine whether chlorine gas can be kept in copper cylinder, we need to calculate the e.m.f when the two half cells combine.

E.m.f= E reduction- E oxidation

= +0.34V- (1.36V)

=-1.02V

The negative value implies that the reaction will not take place. We can therefore conclude that chlorine gas can not be kept / stored in copper cylinder.
