Verified step by step guidance1
Understand the definition of a binary acid: A binary acid is composed of hydrogen and one other nonmetal element.
Review the given options: sulfuric acid (H₂SO₄), nitric acid (HNO₃), phosphorous acid (H₃PO₃), and phosphoric acid (H₃PO₄).
Identify the composition of each acid: sulfuric acid contains hydrogen, sulfur, and oxygen; nitric acid contains hydrogen, nitrogen, and oxygen; phosphorous acid contains hydrogen, phosphorus, and oxygen; phosphoric acid contains hydrogen, phosphorus, and oxygen.
Recognize that none of the given options are binary acids because they all contain more than two elements.
Recall that hydrochloric acid (HCl) is a binary acid because it consists of hydrogen and chlorine, which fits the definition of a binary acid.
