Oxidising power of chlorine in aqueous solution can be determined by the parameters indicated below: <br>
$\large\frac{1}{2}$$ Cl_2(g) \underrightarrow{\qquad \frac{1}{2} \Delta {diss} H^{-} \qquad } Cl(g) \underrightarrow{\qquad \Delta {eg} H^{-}\qquad} Cl^{-}(g) \underrightarrow{\qquad \Delta _{hyd} H^{-}\qquad } Cl^{-}(aq)$ <br>
The energy involved in the conversion of $\frac{1}{2}Cl_2(g) to Cl^{-}(g)$ <br>
(using the data ,<br>
$\Delta_{diss}H^{\Theta}_{Cl_2}=240 KJmol^{-1}$ ,$\Delta_{eg}H^{\Theta}_{Cl}=-349 KJmol^{-1}$ , $\Delta_{hyd}H^{\Theta}_{Cl}=-381 KJmol^{-1}$)
