Identify the conjugate acid of SO₄^2-. A) H₂SO₄ B) HSO₄^- C) H₂SO₃ D) H₃O⁺ E) SO₃^2-

Question

Quizplus · Accepted Answer

To identify the conjugate acid of the given compound, we need to add a proton (H+) to the compound. The proton will add to the lone pair of electrons on the most basic atom in the compound, which in this case is the sulfur (S) atom in the sulfide ion (S2-).
Thus, the conjugate acid will have an extra proton on the sulfur atom while maintaining the rest of the compound's structure. Among the given options, only option B has an extra proton on the sulfur atom in the sulfide ion while maintaining the rest of the compound's structure. Hence, B is the correct answer.
