The correct decreasing order of the acid...

The correct decreasing order of the acidic strength of `HClO, HClO_(2), HClO_(3),HClO_(4)` is

Text Solution

Verified by Experts

`{:(,"Oxidation Number of chlorine"),("HClO (Hypo chlorus acid)"," "+1),("HClO"_(2)" (Chllorous acid)"," "+3),("HClO"_(3)" (Chloric acid)"," "+5),("HClO"_(4)" (Perchloric acid)"," "+7):}`
`therefore" Strength of acid "alpha" Oxidation Number"
So the order will be
`HClO_(4)gt HClO_(3)gt HClO_(2)gt HClO`
