H3PO4 Phosphoric acid is a weak acid due to the fact that it does not fully dissociate in water. In direct contrast with "HCl" vs. "HBr", "HClO" is a stronger acid than "HBrO", because "Cl" is more electronegative, which dominates over the size difference between "Cl" and "Br" due to the presence of the oxygen. Is HBrO4 or HBrO2 expected to be more acidic in an aqueous solution acid-base. This weakens the H-O bond which makes it easier for the H to come off as H+ (i.e. Hydrofluoric Acid HF weak acid.
