Question

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

Answer 1

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

Conjugate acid

• When a proton is added to a base, a conjugate acid is formed.
• Conjugate acids have one extra proton compared to the species that is forming it.

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

• The given species is ammonia$\left({\mathrm{NH}}_3\right)$.
• The conjugate acid of ${\mathrm{NH}}_3$ is ${\mathrm{NH}}_4^{+}$.
