Which statement correctly relates two substances in this chemical equation? nh3 + h2o ⇌ oh− + nh4+ a. h2o is the conjugate base of oh−. b. h2o is the conjugate acid of nh3. c. nh4+ is the conjugate acid of nh3. d. nh3 is the conjugate acid of nh4+. e. oh− is the conjugate base of nh3.

The correct statement is C

NH4+ is the conjugate acid of NH3

Explanation:

NH₃ + H₂O ⇌ OH⁻ + NH₄⁺

Ammonia is the base

Water is the acid

So the conjugate pairs are.

the acid, amonium

the base, the hydroxide

Water is also known as an amphoterus compound. It can act as an acid, or as a base at the same time. (Bronsted-Lory)
