Solution

The correct option is A True
Bleaching powder decomposes in the presence of cobalt chloride catalyst to liberate oxygen.
$2 C a O C l_{2} \to 2 C a C l_{2} + O_{2}$

When kept for a longer time with cobalt chloride, bleaching powder turns into calcium chlorate and calcium chloride.
$6 C a O C l_{2} \to C a (C l O_{3})_{2} + 5 C a C l_{2}$
