Identify the oxyacids given: HClO3, HBrO4, HBrO3, and HClO4.
Understand that the acidity of oxyacids generally increases with the number of oxygen atoms bonded to the central atom, as more oxygen atoms can stabilize the negative charge on the conjugate base through resonance.
Compare the number of oxygen atoms in each oxyacid: HClO3 has 3 oxygens, HBrO4 has 4 oxygens, HBrO3 has 3 oxygens, and HClO4 has 4 oxygens.
Recognize that for oxyacids with the same number of oxygen atoms, the acidity increases with the electronegativity of the central atom. Chlorine is more electronegative than bromine.
Rank the oxyacids based on the number of oxygen atoms and the electronegativity of the central atom: HBrO3 < HClO3 < HBrO4 < HClO4.
