Bleaching powder and bleach solution are...

Bleaching powder and bleach solution are produced on a large scale and used in several hous-hold products. The effectiveness of bleach solution id often measured by iodometry.
Bleaching powder contains a salt of an oxoacid as one of its components. The anhydride of that oxoacid is:

A

`CI_(2)O`

B

`CI_(2)O_(7)`

C

`CIO_(2)`

D

`CI_(2)O_(6)`

Text Solution

Verified by Experts

The correct Answer is:
a
The active constituent of bleaching powder is `Ca(OCI)_(2)` since the anion of this salt is `OCI^(-)` therefore its corresponding acid isHOCI and the anhydride of this acid must be `CI_(2)O`
`2HOCIrarrH_(2)+CI_(2)O`
