Sodium Chloride 99.5% AR Grade Reagent
Cas Number:7647-14-5
Formula: NaCl
Molar Mass:58.44
EC Number:231-598-3
Physicochemical properties:
White cubic crystal or crystalline powder. At 25 ° C, 1 g is dissolved in 2.8 ml of water, 2.6 ml of boiling water, 10 ml of glycerol, and very slightly soluble in ethanol. The solubility in water is reduced by the presence of hydrochloric acid and is hardly soluble in concentrated hydrochloric acid. The aqueous solution is neutral and with a pH of 6.7 to 7.3. The relative density is 2.17.The melting point is 804 ° C. The boiling point is 1413 ° C. The median lethal dose (rat, oral) was 3.75 ± 0.43 g / kg.
Usage:
A benchmark for the determination of silver nitrate. Determination of fluorine and silicates in trace amounts. High purity analysis. Routine blood test. Liver function test. Making bacterial serological medium. Cooling mixture. Food preservation.
Packing:
500g/25kg
