Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Bleaching powder is prepared by passing chlorine gas over dry slaked lime $Ca(OH)_2$ by Hesenclaver method or by Bachmann method.
$Ca(OH)_2 + CI_2 \longrightarrow CaOCI_2 + H_2O$
$Ca(OH)_2 + CI_2 \longrightarrow CaOCI_2 + H_2O$
