Pyrophosphoric acid is colorless, odorless, hygroscopic, syrupy liquid or crystal form. Density 2.04g/cm3 (25 ℃). Melting point 61 ℃. It is soluble in water, diethyl ether, and ethyl alcohol. Pyrophosphoric acid is from phosphoric acid by dehydration. Pyrophosphoric acid is a medium strong inorganic acid, it slowly hydrolyzes in the presence of water into phosphoric acid.
The anion, the salts, and the esters of pyrophosphoric acid are called pyrophosphates.
Pyrophosphoric acid is used as a catalyst, such as of organic phosphate.
Pyrophosphoric acid is also used as intermediate agent or diagnostic agent of heart disorders in pharmaceutical industry.
