Mayer's reagent
Mayer's reagent is an alkaloidal precipitating
mercuric chloride (1.36 g) and of potassium iodide (5.00 g) in water (100.0 ml).[1][2] Most alkaloids are precipitated from neutral or slightly acidic solution by Mayer's reagent (potassiomercuric iodide solution) to give a cream coloured precipitate. This test was invented by the German Chemist, Julius Robert Von Mayer
(1814–1878).
