Phenylamine and sulfuric acid
Web1. jan 2024 · Two pairs of hydrogen bond interaction are formed between hydroxyl group of sulfuric acid and carbonyl oxygen of amide. The variation of OH bonds can be explained by the alkaline strength of amides, NH 3 , aniline, methylamine and dimethylamine, in which the basicity of methylamine and dimethylamine is stronger than that of ammonia, … WebTry this class practical to explore an equilibrium involving copper (II) ions. In this experiment, students add ammonia to a solution of copper (II) sulfate, observe the colour changes taking place, and then reverse the reaction by the addition of sulfuric acid. The experiment is best carried out by students working individually.
