stability
1. Stable in the air at room temperature. When heated to 150℃, the crystalline water is lost. Insoluble in ethanol, easily soluble in water, 5% of the aqueous solution pH value is 7.6 ~ 8.6. Soluble in water and glycerol, slightly soluble in ethanol, ether. Lose two crystalline waters at 150℃.
2. It has excellent solubility, and solubility increases with the increase of water temperature. It has good ph adjustment and buffering performance. Sodium citrate is a kind of weak acid and strong base salt. Combining with citric acid, it can form a strong ph buffer. Therefore, it has an important use in some situations where ph is not suitable for wide range changes. In addition, sodium citrate also has excellent retarding and stable properties.
