Question

Urea behaves as a mono acidic base.Explain

Answer 1

The material itself is neutral. However, it will slowly hydrolyze to ammonia and carbonic acid. Carbonic acid will, in turn, disproportionate to carbon dioxide and water. So a fresh solution of urea should be nearly neutral. An aged solution will have a basic pH. hope help##

Answer 2

Urea is mono-acidic base. It it actually Arrhenius base that deprotonates water leaving OH- in its water solution , which in turn works as base.
