Question

Predict whether or not `Cl_(2)` would disproportionate in cold alkaline medium. The standard reduction potentials of` Cl_(2)|Cl^(c-)` and `ClO^(c-)|Cl_(2)` are `1.36V` and `0.40V`, respectively.

Answer 1

Anode `: 4 overset(c-)(O)H+Cl_(2) rarr 2ClO^(c-)+2H_(2)O+2e^(-)`
Cathode `: Cl_(2)+2e^(-)rarr 2Cl^(c-)`
`E^(c-)=E^(c-)._(c)-E^(c-)._(a)`
`E(c-)=` positive, cell is feasible.
Disproportionate of `Cl_(2)(i.e.,` simulaaneous oxidation and reduction of `Cl_(2)) ` is feasible.
