A) \[CaC{{l}_{2}}\]
B) \[CaS{{O}_{4}}\]
C) \[HClO\]
D) \[Ca{{(Cl{{O}_{3}})}_{2}}\]
Correct Answer: C
Solution :
In the presence of dilute acids, bleaching powder loses oxygen, \[2CaOC{{l}_{2}}+{{H}_{2}}S{{O}_{4}}\xrightarrow{\,}\,CaC{{l}_{2}}\] \[+CaS{{O}_{4}}+2HClO\] \[HClO\xrightarrow{\,}\,HCl+[O]\] This oxygen is used for oxidation-bleaching.
