Solution

The correct option is D (H2O,OH) and (NH+4,NH3)
NH3+H2ONH+4+OH
Conjugate Acid-Base =(H2O,OH)and(NH+4,NH3)
A conjugate acid, within the Brønsted–Lowry acid–base theory, is a species formed by the reception of a proton (H+) in a chemical reaction. Hence, a conjugate base is a species formed by the removal of a proton from an acid.
In summary, this can be represented as the following chemical reaction:
Acid + Base ⇌ Conjugate Base + Conjugate Acid
conjugate base : substance formed when an acid loses a hydrogen ion . Considered a base because it can gain a hydrogen ion to reform the acid .
Ex Cl is the conjugate base of HCl
