Solution

The correct option is A $C l^{-}, O C l^{-}$
"Bleaching powder" is a mixture of calcium hypochlorite $C a (O C l)_{2}$ and the basic chloride $C a C l_{2}, H_{2} O$ with some slaked lime $C a (O H)_{2}$ .

The general formula of Bleaching powder is $C a O C l_{2}$ .

$C a O C l_{2} ⟶ C a^{2 +} + O C l^{-} + C l^{-}$

So, option A is correct.
