Question

What is the conjugate base of ${\mathrm{NH}}_3$?

Answer 1

A conjugate acid-base pair is an acid-base pair that differs only by one proton.

Conjugate base

• When a proton is removed from an acid, a conjugate base is formed.
• Conjugate bases have one proton less and one more negative charge compared to the species that is forming it.

Conjugate base of ${\mathrm{NH}}_3$

• The conjugate base of ${\mathrm{NH}}_3$ is ${\mathrm{NH}}_2^{-}$.
