Expert Answer:

The base formed from an acid by donating a proton is called the conjugate base of the acid.

Acid = Conjugate base + H+

The acid formed from a base by accepting a proton is called the conjugate acid of the base.

Base + H+ = Conjugate acid

1. NH3 - Conjugate acid NH4+

2. H2O - It behaves as an acid and base both. Its conjugate acid will be H3O+ and conjugate base will be OH-.

3. HCO3- - It behaves as an acid and base both. Its conjugate acid will be H2CO3 and conjugate base will be CO32-

4. PH3 - Conjugate acid PH4+
