In the parent aniline, the lone pair is approximately 12% s character, corresponding to sp7.3 hybridization. 2 no2 + h20 gives hno3 + hno2. Traditionally, the weak basicity of aniline is attributed to a combination of inductive effect from the more electronegative sp2 carbon and resonance effects, as the lone pair on the nitrogen is partially delocalized into the pi system of the benzene ring. However, even if we mix stoichiometrically equivalent quantities, we may find that the resulting solution is not neutral. A solution of a weak acid reacts with a solution of a strong base to form the conjugate base of the weak acid and the conjugate acid of the strong base.
