Question

What will be the conjugate bases for the Bronsted acids: HF, $H_{2}SO_{4}$ and $HCO_{3}^{-}$ ?

Answer 1

Conjugate acid: It contains one Hydrogen atom (H) more and also one more positive charge than the base from which it formed.  

Conjugate base: It contains one hydrogen atom (H) less and one more negative charge than the acid from which it formed.

In HF, the conjugate base is ${ F }^{ - }$ .

In ${ H }_{ 2 }{ SO }_{ 4 }$, the conjugate base is ${ H }{ SO }_{ 4 }$.

In ${ H }C{ O }_{ 3 }^{ - }$, the conjugate base is $C{ O }_{ 3 }^{ 2- }$.
