Product Details

Product Introduction:

Product Name:Potassium Dihydrogen Phosphate (Technical Grade)

English Name:MKP Monopotassium Phosphate (Technical Grade)

Molecular Formula:KH₂PO₄

CAS No.:7778-77-0

Executive Standard:HG/T 2321-2016

Physical and Chemical Properties:

Appearance:White or colorless crystalline powder

Molecular Weight:136.09

Density:2.338 g/cm³

Melting Point:252.6℃

Solubility:Easily soluble in water (approx. 222g/L at 20℃), insoluble in ethanol; aqueous solution is acidic

pH Value (1% aqueous solution):4.2～4.8

Stability:Stable at room temperature, slightly hygroscopic; when heated to about 400℃, dehydrates and melts, solidifying into opaque potassium metaphosphate upon cooling

Storage:Store sealed in a cool, dry place; protect from moisture and sun exposure, and keep away from toxic substances
