218002129
Potassium Chloride 99.5% AR Grade Reagent
Cas Number:7447-40-7
Formula: KCl
Molar Mass:74.55
EC Number:231-211-8
Physicochemical properties:
White crystalline or crystalline powder with bitter taste. It is hygroscopic. 1 g is dissolved in 2.8 ml of water, 1.8 ml of boiling water, 14 ml of glycerin, about 250 ml of ethanol, and is insoluble in ether, acetone and hydrochloric acid. Sodium and magnesium chlorides reduce their solubility in water. The saturated aqueous solution at 15 ° C has a relative density of 1.172 and a pH of about 7. The relative density is 1.98. The melting point is 770 ° C. The boiling point is 1500 ° C (partial sublimation). Irritating.
Usage:
Buffer solution. Platinum is determined by spot analysis. Benchmark the calibration of silver nitrate standard solutions. High purity analysis. Emission spectrum analysis. Spectrum analysis. Made the medium. Pharmaceutical. Photosensitive material.
Packing:
500g/25kg
