Four species are listed below
i.

H C O_{3}^{-}

ii.

H_{3} O^{+}

iii.

H S O_{4}^{-}

iv.

H S O_{3} F

Which one of the following is the correct sequence of their acid strength?

Accepted Answer

The correct order of acidic strength of the given species in

\underset{(i v)}{H S O_{3} F} > \underset{(i i)}{H_{3} O^{+}} > \underset{(i i i)}{H S {O_{4}}^{-}} > \underset{(i)}{H C {O_{3}}^{-}}

or

(i) < (i i i) < (i i) < (i v)

It corresponds to choice

(c)

which is correct answer.
