NEET levelSingle correct optionDifficulty 1 of 3ph008

Bleaching powder is manufactured by passing chlorine over

Aa hot concentrated solution of $NaOH$
Bdry slaked lime, $Ca (OH) X_{2}$
Climestone, $CaCO X_{3}$
Dquicklime, $CaO$ , at 1000 K

Answer: B

The reaction is

Ca (OH) X_{2} + Cl X_{2} CaOCl X_{2} + H X_{2} O

, carried out with dry slaked lime (Hasenclever plant or similar). The other substances do not give bleaching powder.
