Oxidation numbers of two cl atoms in bleaching powder

\left( {CaOC{l_2}} \right)

are,

View answer and explanation

Correct option: B

+ 1,\mathrm{ } - 1

Option B (+1, -1) is correct because bleaching powder is a mixed salt containing both hypochlorite (OCl-) and chloride (Cl-) ions, resulting in +1 and -1 oxidation states for the two chlorine atoms.
