The pKa of HIO(aq), hypoiodous acid, is 10.64 and that of HIO3(aq), iodic acid, is 0.77. Account for the difference in acid strength.

More oxygen=more electronegative, which stabilizes the negative charge on I, making it MUCH easier for the H to break off and protonate water to create hydronium, thus more acidic.
