Given the reaction:HSO4- +H2O <--> H3O+ + So²-4
Which is a bronsted lowry cojugate acid base pair?
1.HSO4- and H3O+
2.HSO4- and SO²-4
3.H2O and SO²4-
4.H2O and HSO4-

According to Bronsted Lowry theory, an acid loses a proton (H⁺) to becomes its conjugate base.
Now: HSO₄⁻ → SO₄²⁻ + H⁺
HSO₄⁻ loses a proton becomes SO₄²⁻. Hence, HSO₄⁻ is an acid and SO₄²⁻ is its conjugate base.
The answer: 2. HSO₄⁻ and SO₄²⁻
2.HSO4- and SO²-4
Conjugate pairs differ by only one proton. The acid (HSO4-) has it and the base (SO²-4) doesn't.
