Phosphoric Acid 85% AR Grade Reagent
Cas Number:7664-38-2
Formula: H3PO4
Molar Mass:98
EC Number:231-633-2
Physicochemical properties:
In the absence of water, it is an unstable orthorhombic crystal (melting point 42.35 ° C) or a colorless transparent viscous liquid. It is easy to be too cold to form a glass. Odorless. Sour. There will be a comfortable sour odour after proper dilution. 88% of the phosphoric acid is placed in a cold place for a long time, and crystals can often be formed (melting point 29.32 ° C, hemihydrate phosphoric acid). It becomes an anhydrate at 150 ° C and gradually changed to pyrophosphoric acid at about 200 ° C. It becomes metaphosphoric acid above 300 °C.
Usage:
Determination of chromium, nickel and vanadium in steel. Metal rust. A catalyst for producing ethanol. Non-protein nitrogen, urea nitrogen, total cholesterol and whole blood glucose are measured in serum.
Packing:
500ml/25L/200L
