Introduction
Easy to absorb moisture. It can absorb 2-7 molecules of crystal water in the air for a long time, and it will be decomposed into sodium pyrophosphate when heated to 300℃. It is soluble in about 8 parts of water, soluble in hot water, insoluble in ethanol, and 1% aqueous solution with pH 9.1 at 25°C. The minimum lethal dose (rats, abdominal cavity) is 1000 mg/kg. Solubility in water: 75 g/L (20°C). Analytical reagents, buffers, softeners, fire retardants for printing and dyeing industry, fabric weighting agents.
