The strengths of oxyacids is based on the number of oxygens or the electronegativity of the nonmetal in the oxyacid. An oxyacid is considered strong when there are at least 2 or more O than H.
For acids with an equal number of oxygen, the acid strength is based on the electronegativity of the nonmetal in each oxyacid.
Arrange the following substances in order from weakest to strongest acid: HIO, HClO3, HBrO2, HClO2, HIO2
