  1. Objective/Warm-Up • SWBAT predict the strength of acids based on the bonding of atoms in the compound. • Of the following oxo acids, which is predicted to be the strongest acid? A) HBrO B) HClO C) HIO D) HClO3 E) HIO3

  2. Answer is “D” Among HBrO, HClO, and HIO, the more electronegative central atom indicates a stronger oxo acid. Therefore HClO is the strongest of these three. For the same reason, we choose HClO3 over HIO3 as the strongest acid in this pair. Comparing HClO and HClO3, we select HClO3 as the strongest because it has the larger number of unshared or double-bonded oxygen atoms that stabilize the anion, creating a stronger acid.

  3. Oxides • Acidic Oxides (Acid Anhydrides): • OX bond is strong and covalent. • SO2, NO2, CrO3 • Basic Oxides (Basic Anhydrides): • OX bond is ionic. • K2O, CaO
