Product Description of Trisodium Phosphate CAS#7601-54-9

Trisodium Phosphate Dodecahydrate is white to colorless hexagonal crystals with a density of about 1.62 g/cm³. It melts near 75 °C on rapid heating and partially loses crystal water at 100 °C, retaining the last water molecule even at higher ignition temperatures. Freely soluble in water with solubility of around 28 g/100 mL at 20 °C, forming a strongly alkaline solution; 0.1 M aqueous solution pH approx 11.5. Insoluble in alcohol, widely applied where strong alkalinity and good water solubility are required.
