Ammonium Chloride 99.5% AR Grade Reagent
Cas Number: 12125-02-9
Formula: NH4Cl
Molar Mass:53.49
EC Number:235-186-4
Physicochemical properties:
Colorless crystal or white granular powder. Odorless with cool, salty taste. Slightly hygroscopic. It can sublimate without melting point. Hydrochloric acid and sodium chloride reduce the solubility in water. The solubility in water is 20% (w/w) at -13 °C, 25% at 10 °C, 30% at 33 °C, and 40% at 80 °C with a strong endothermic (ie, when dissolved, lowers the temperature of the solution). The pH of the aqueous solution is 25 ° C, 1% is 5.5, 3% is 5.1, and 10% is 5.0. Soluble in methanol.
Usage:
Isolation and precipitation of ions.Buffer. Determination of uric acid. Refrigerant. Pharmaceutical.
Packing:
500g/25kg
