Question

which one of the following is the strongest acid?

a) HIO3 b) HIO2 c) HIO d)IO4- e)I-

explain your answer.

Answer 1

Answer #1

HIO3 is the strongest acid.

Among the oxyacids of an element, the higher the oxidation state, the more acidic is the acid.

Thus

HIO4 > HIO3 > HIO2 > HIO .

Here only three are given among them HIO3 is strongest.

IO4- is the conjugate base of strong acid HIO4. so it is a base not acid.

Similarly I- is the conjugate base of acid HI.
