LASSAIGNE’S TEST Sample Clauses

LASSAIGNE’S TEST. Place about 10 mg or one (1) (small) droplet of the unknown (A, B or C) and about 50 mg of freshly cut sodium metal into a glass tube (Note 1). Heat the tube as strongly as possible until the bottom of the tube is glowing red, holding the tube at this heat for about 5 min. For liquid unknown, start with moderate heating to avoid fast evaporation. Quickly plunge the hot tube into an evaporating dish containing distilled water (~ 10 mL) (Note 2) and cover the dish. Boil the solution on a hot plate for a few minutes while gently crushing the residue with a glass rod. Filter and a colorless filtrate should be obtained. If the volume of filtrate is too little, add distilled water to the filtrate. Use the filtrate for the tests below. A colored filtrate indicates incomplete decomposition and the entire fusion procedure will have to be repeated. Notes:
