Sodium Phosphate Monobasic (Anhydrous) , (99%) , AR, CAS: 7558-80-7

Product Description

Description

Sodium Dihydrogen Phosphate (Anhydrous)

Characteristics:Characteristics: Tasteless. Slight moisture absorption. To form acidic pyrophosphate if it is heated to 225-250 °C, and form sodium metaphosphate when it is heated to 350-400°C. Median lethal dose ( rat muscles ) 250mg/kg.Easily soluble in water, the aqueous solution is acidic, and can agglomerate in moist air, almost insoluble in ethanol. Dehydration when heated to 100 °C, sodium pyrophosphate is generated when heated to 190-210 °C, and in the 280-300 C it will be decomposed to sodium metaphosphate. Solubility in water : 850 g/L ( 20°C)
Purpose:Purpose:Buffering agent, water softener. Used to make stimulants and fruit salt in pharmaceutical industry.Used as a detergent, PH buffer additives, dyes and auxiliaries, and also Boiler water treatment, mica Henri Frederic amiel, baking powder and electroplating and so on.
