Descripción general

Easy to absorb moisture. Long term exposure to air can absorb 2-7 molecules of crystalline water, which decomposes into sodium pyrophosphate when heated to 300 ℃. Dissolved in about 8 parts of water, soluble in hot water, insoluble in ethanol, a 1% aqueous solution with a pH of 9.1 at 25 ℃. Minimum lethal dose (rat, intraperitoneal) 1000mg/kg. Solubility in water: 75 g/L (20 ° C). Analytical reagents, buffering agents, softeners, fire-resistant agents for printing and dyeing industries, and fabric weighting agents.
