Bleaching powder contains a salt of an oxoacid as one of its compounds. The anhydride of that oxoacid is :

A

`Cl_2O`

B

`Cl_2O_7`

C

`ClO_2`

D

`Cl_2O_6`

Text Solution

Verified by Experts

The correct Answer is:
A
The active constituent of bleaching powder is `Ca(OC l_2)`. Since OCl is an anion, hence, the acid is HOCI and its anhydride is
`underset("Acid")(2NOCl) to H_2O+ underset("Anhydride")(Cl_2O)`
