Question

Question 7.37 What will be the conjugate bases for the Brönsted acids: HF, H2SO4 and HCO3?

Class XI Equilibrium Page 228

Answer 1

concept:- acid ⇔ conjugate base + H⁺

HF is an acid, so, it can lose one proton (H⁺) and form conjugate base.
e.g.,  HF (acid)  ⇔ H⁺   + F⁻ (conjugate base )

H₂SO₄ is an acid, so, it can lose one proton (H⁺) and form conjugate base.
e.g., H₂SO₄ (acid) ⇔ HSO₄⁻ (conjugate base) + H⁺

HCO₃⁻ is an acid, so, it can lose one proton (H⁺) and form conjugate base.
e.g., HCO₃⁻(acid) ⇔ CO₃⁻⁻ (conjugate base) + H⁺
