Product Description
DISODIUM HYDROGEN PHOSPHATE
1.BASSIC INFORMATION
Alias: DSP
Formula: Na2HPO4·12H20
Molecular weight: 358.14
CAS NO.: 10039-32-4
HS Code: 28352200
EINECS: 231-448-7
2.PROPERTIES
Appearance: White powder, flake or granular crystal
Type: Industrial Grade
Density: 1.52 g/cm3
Melting point: 34.6°C
Solubility: Soluble in water, its aqueous solution is alkaline. >=10 g/100 mL (20ºC).
Characteristics: It is easy to weather in the air and then lose five molecules of crystal water to form Na2HPO4·7H20. At 100 °C, the crystal water is lost to form anhydrous substance and it breaks down into TSPP at 250 °C.
