Step 1
What is the conjugate base of HSO₄⁻?
Answer
To identify the conjugate base of a given acid, we must remove a proton (H⁺) from that acid. The given acid is bisulfate (HSO₄⁻). Upon removing one H⁺ ion from HSO₄⁻, we are left with sulfate (SO₄²⁻).
Thus, the conjugate base of HSO₄⁻ is SO₄²⁻, which corresponds to option (B).
