In basic medium, $C l_{2}$ disproportionates into $C l^{-}$ and $Cl O_{x}^{-}$ . If there is loss and gain of five moles of electrons per three moles of $C l_{2}$ , the value of $x$ is

Options:

Answer:

Solution:

A loss of 5 $e^{-}$ by one Cl atom takes it to +5, i.e. $Cl O_{3}^{-}$ , so $x$ = 3. Check: $3C l_{2}$ + $6O H^{-}$ $\to$ $5C l^{-}$ + $Cl O_{3}^{-}$ + $3 H_{2} O$ transfers 5 $e^{-}$ per 3 $C l_{2}$ . Hence (b).
