Which is the strongest acid HlO, HlO3, HlO4

The best answer is: HIO3

Explanation:

"Oxygen is a highly electronegative atom, it pulls electron density towards itself and away from iodine. The more oxygen atoms there are, the more spread out the negative charge is on the conjugate base. And the more spread out the charge is, the more stable the base is. This makes the acid a stronger one."

I believe this is the correct answer. Correct me if I'm wrong!

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
