Trisodium phosphate (Food grade)

Products

I. Chemical Name: Trisodium phosphate

Ⅱ. Molecular formula: Na₃PO₄·12H₂O

Ⅲ. Molecular Weight: 380.14

IV. Properties: colorless needle-like hexagonal crystal; Relative Density 1.62 (20℃); Melting point73.3-76.7℃ (decompound); can not melt in organism aqua. Opposite density is 1.62 (20℃). The temperature reach the 73.3-76.7℃ it will melt. It vaporizes. When the temperature reach 100℃ it will loose water change into Na₃PO₄. Aqueous is alkaline, erode to the skin.
