Since the ends are condensed, its formula has one less H 2 O (water) than tripolyphosphoric acid. The general formula of a phosphoric acid is H n−2x+2 P n O 3n−x+1, where n is the number of phosphorus atoms and x is the number of fundamental cycles in the molecule's structure; that is, the minimum number of bonds that would have to be ...
Phosphoric acid (orthophosphoric acid, monophosphoric acid or phosphoric(V) acid) is a colorless, odorless phosphorus-containing solid, and inorganic compound with the chemical formula H 3 P O 4. It is commonly encountered as an 85% aqueous solution , which is a colourless, odourless, and non- volatile syrupy liquid.
These acids, and their esters and salts ("phosphates") include some of the best-known and most important compounds of phosphorus. Orthophosphoric acid, H 3 PO 4. The simplest member of this class is: Phosphoric acid proper (also called orthophosphoric acid or monophosphoric acid), H 3 PO 4 (or OP(OH) 3), a triprotic acid.
A major appeal of this route is the low cost of phosphoric acid compared to phosphorus oxychloride. OP(OH) 3 + ROH → OP(OH) 2 (OR) + H 2 O. P 2 O 5 is the anhydride of phosphoric acid and acts similarly. The reaction yields equimolar amounts of di- and monoesters with no phosphoric acid.
At pH 1 or lower, the phosphoric acid is practically undissociated. Around pH 4.7 (mid-way between the first two pK a values) the dihydrogen phosphate ion, [H 2 PO 4] −, is practically the only species present. Around pH 9.8 (mid-way between the second and third pK a values) the monohydrogen phosphate ion, [HPO 4] 2−, is the only species ...

Phosphate is an inorganic anion of phosphoric acid OP(OH) 3. There are also organophosphorus compounds with the formula OP(OR) 3. Subcategories.
Soft drinks containing phosphoric acid, including Coca-Cola, are sometimes called phosphate sodas or phosphates. Phosphoric acid in soft drinks has the potential to cause dental erosion. [105] Phosphoric acid also has the potential to contribute to the formation of kidney stones, especially in those who have had kidney stones previously. [106]
