Introduction ( Phosphoric Acid CAS No.7664-38-2)
Phosphoric acid, also known as orthophosphoric acid or phosphoric(V) acid, is a weak acid with the chemical formula H3PO4. It is normally encountered as a colorless, syrup of 85% concentration in water. The pure compound is a colorless solid.Phosphoric acid is commonly encountered in chemical laboratories as an 85% aqueous solution, which is a colourless, odourless, and non-volatile syrupy liquid. Although phosphoric acid does not meet the strict definition of a strong acid, the 85% solution can still severely irritate the skin and damage the eyes.
Molecular formula:H3PO4
Molecular weight:97.99
Content:75%,81%,85%.
Properties: Colorless transparent viscous liquid. It is odorless, very sour, melting point 42.35 C, soluble in water, soluble in
ethanol. It can stimulate skin inflammation, destroy body tissues, and has hygroscopicity.
