Vedclass · Answer

(A) The reaction represents the catalytic decomposition of bleaching powder $(CaOCl_2)$ in the presence of cobalt chloride $(CoCl_2)$.Bleaching powder is represented as $Ca(OCl)Cl$.When $CaOCl_2$ reacts with $CoCl_2$,it decomposes to form calcium chloride $(CaCl_2)$ and oxygen gas $(O_2)$: $2CaOCl_2 \xrightarrow{CoCl_2} 2CaCl_2 + O_2 \uparrow$.The effective oxidizing or active ingredient in bleaching powder is the hypochlorite ion,$OCl^-$,which is responsible for its bleaching and oxidizing properties.

$X \xrightarrow{CoCl_2} CaCl_2 + Y \uparrow$; the effective ingredient of $X$ is
