Can you tell me the conjugate base of #NH_3#? This does not occur in aqueous solution, but it is conceived to occur in liquid ammonia. And what is the conjugate base of this species?Basicity may be related to the pKa of the corresponding conjugate acid, as shown below. The strongest bases have the weakest conjugate acids and vice versa. Nucleophilicity is a more complex property. It commonly refers to the rate of substitution reactions at the halogen-bearing carbon atom of a reference alkyl halide, such as CH 3-Br.

Acid-base reactions à la Brønsted.
