Chlorine water (aqueous chlorine) contains which of the following?

A $HOCl$
Bdissolved molecular $Cl X_{2}$
Can appreciable amount of $ClO X_{4} X^{-}$
D $Cl X^{-}$ ions

Answer: A, B, D

The equilibrium

Cl X_{2} + H X_{2} O H X^{+} + Cl X^{-} + HOCl

is set up, so

HOCl

,

Cl X_{2}

,

H X^{+}

and

Cl X^{-}

are present. Perchlorate requires further oxidation to +7, which does not occur, so the last statement is wrong.
