The amide ion, #NH_2^-#.


The conjugate base of any species is that species less a proton. Ammonia less a proton is the amide ion, #NH_2^-#. Mass and charge are conserved as always. This species does NOT exist in water, but it is the characteristic anion in liquid ammonia, a water like solvent that will support more powerful bases than does water. The amide ion also has a conjugate base, called the imide ion. Care to tell me what it is? The imide ion itself has another conjugate base, called the azide ion. What is it?
