Phosphoric acid

Product name: phosphoric acid food grade
Formula: H3PO4
molecular weight: 98.0
CASRN: 7664-38-2

physicochemical properties: Colorless,transparent and syrupy liquid. Melting point:42.35 
centigrade. boiling point 213 centigrade,generating pyrophosphoric acid at boilling point. 
Heating 300 centigrade to become metaphosphoric acid.Relative density:1.87 . it is soluble in 
ethanol and easily soluble in water.its acidity is weaker than sulfuric acid, hydrochloric acid 
and nitric acid, but is stronger than boric acid acetic acid, etc. Can cause skin inflammation 
and disrupt the organizational structure of the skin. it begin to crystallize once it cooled down
for a long time.hygroscopic and corrosive liquid.
