Metaphosphoric acids general formula is (HPO3)n ; where n denoted number of phosphoric acid units present in the ring with n being greater or equal to 3. Sometimes (in old textbooks/in poor-made school course of chemistry) you can hear "metaphosphoric acid", which is on the pic above, but the name and pic itself are false. We often think of water quality from the standpoint of chemical properties, such as alkalinity, mineral elements, pH, etc. It means 1.7 g of it (see chemspider.com).

Another way to understand water alkalinity is that it is a measure of the ‘’limestone’’ content in the water. Metaphosphoric acid. Does this picture depict the conditions at a veal farm? The known metaphosphoric acids are characterized by cyclic molecular structures. A phosphoric acid, in the general sense, is a phosphorus oxoacid in which each phosphorus atom is in the oxidation state +5, and is bonded to four oxygen atoms, one of them through a double bond, arranged as the corners of a tetrahedron. Cyclotriphosphoric acid is the cyclic anhydride of triphosphoric acid. Source: Premier Tech. What do the prefixes meta, ortho, pyro mean in inorganic chemistry? With those usages, it’s not so surprising that this acid is commonly found on lists of “ strong acids ” or chemicals commonly used in industry that can cause chemical burns.
