Appearance	Solid Crystal
Identification	A: Hcat about 500mgi in a test tube itllquefies and ammonia is evolved. Continue the heating until the liquid becomes turbid then cool. Dissolve the mass in a mixture of 10ml of water and 1ml of sodium hydroxide solution and I drop of cupric sulfate The solution acquires a reddish-violet color
Identification	B: Dissolve 100mg in 1ml of water and add 1ml of nitric acid a white crystalline precipitate of urea nitrate is formed
