Oxyacids represent the second class of covalent acids
Concept #1: Oxyacids represent covalent compounds containing a hydrogen ion and an oxygen containing anion.
Example #1: Which of the following represents the possible structure of an oxyacid?
a) NaNO3 b) HCHO2 c) KOH d) HCN
Concept #2: The Oxygen Strength Rule is a convenient tool to help determine if an oxyacid is weak or strong.
Example #2: Which of the following represents a strong oxyacid?
a) HNO2 b) HC2H3O2 c) HClO d) HSO4– e) HBrO3
Concept #3: When comparing the strength of oxyacids the key is in comparing their number of oxygens.
Example #3: Rank the following oxyacids in terms of increasing acidity.
i. HClO3 ii. HBrO4 iii. HBrO3 iv. HClO4 v. HIO
