Question

Which ions formed from hypochlorous acid form the basis for the bleaching action of chlorine?

• A. $Cl{O}^{-}$
• B. $Cl{O}^{+}$
• C. $H^{+}$
• D. $O^{-}$

Answer 1

The correct option is B $Cl{O}^{+}$

Chlorine reacts with water to give hydrochloric acid and hypochlorous acid(HClO).

$C{l}_2+H_{2}O\to$ $HCl+HClO$

The $Cl{O}^{-}$ ions formed from hypochlorous acid oxidize substances and this forms the basis for the bleaching action of chlorine.
