31. Crystalline samples have been produced by the reaction of ammonium chloride and hexachlorocyclotriphosphazene : or phosphorus pentachloride. 32. This allows for the simple isolation of pure polysilazane from the liquid ammonia / ammonium chloride solution. 33. Ah, here we have solid ammonium chloride ! 34. Ammonium chloride in solution breaks up.35. Do not overwork a patina, especially when using ammonium chloride , or you will destroy the look, Pace said. 36. Dimethyl tallow ammonium chloride is a typical cationic softener and polyethylene glycol monostearate is a typical nonionic softener. 37. The aluminum is precipitated as the hydrated oxide by means of ammonia solution in the presence of ammonium chloride . 38. The potassium nitrate and ammonium chloride are dissolved in warm water and the ethanol and camphor are then added. 39. This is dissolved in water and then treated with ammonium chloride to give an orange-coloured precipitate of ammonium metavanadate. 40. Titrations for cobalt and nickel are carried out in an ammoniacal environment; buffered with ammonia : ammonium chloride solution.
