Pyrophosphoric acid, also known as diphosphoric acid, is the inorganic compound with the formula H 4 P 2 O 7 or, more descriptively, [(HO) 2 P(O)] 2 O. Colorless and odorless, it is soluble in water, diethyl ether, and ethyl alcohol. Pyroglutamic acid (also known as PCA, 5-oxoproline, pidolic acid) is a ubiquitous but little studied natural amino acid derivative in which the free amino group of glutamic acid or glutamine cyclizes to form a lactam. The names of pyroglutamic acid conjugate base, anion, salts, and esters are pyroglutamate, 5-oxoprolinate, or pidolate. This is the first part of a study on Pyrogallic Acid, formula ABC; a black and white negative developer.

Structure of pyrosilicate is shown below. Adjust the pH of the solution to 3.8 with hydrochloric acid, using a pH meter, then add 50 ml of a 1 in 8 solution of zinc sulfate (125 g of ZnSO 4 · 7H 2O dissolved in water, diluted to 1000 ml, filtered, and adjusted to pH 3.8) and allow to stand for 2 min. Titrate the liberated acid with 0.1 N sodium hydroxide until a pH of 3.8 is again Chemistry Formula 1) Alum = K2SO4.Al2(SO4)3.24H2O 2) Sandhur = Pb304 Pyro Boric Acid = H2B4O7 26) Water Glass = Na2SiO3 27) Oil Of Vitriol = H2SO4 Sodium Pyrophosphate is a crystalline acid salt Na2H2P2O7 of pyrophosphoric acid that has been added to hot dogs to give them color -called also sodium acid pyrophosphate source:merriem-webster-online.

The anhydrous acid crystallizes in two polymorphs, which melt at 54.3 °C and 71.5 °C. The compound is not Boric Acid [H 3 BO 3] Weak acid in a powder form which is added to compositions containing aluminum or magnesium and a nitrate. Metals react with nitrates to form amides, which can further react with the metal powder to create a highly exothermic reaction which could spontaneously ignite the compound. For example type II burns at 250 degrees giving off choking fumes.
