Step 1
What is the conjugate base of HSO₄⁻?
Answer
To determine the conjugate base of HSO₄⁻ (hydrogen sulfate ion), we need to understand the concept of conjugate acid-base pairs.
A conjugate base is formed when an acid donates a proton (H⁺). In this case, HSO₄⁻ can donate a proton, resulting in SO₄²⁻ (sulfate ion). Therefore:
The conjugate base of HSO₄⁻ is SO₄²⁻.
Among the given options, the correct answer is (B) SO₄²⁻.
