metaphosphoric acid basicity

Since phosphoric acid, represented by the molecular formula H3PO4, has three hydrogen atoms, it dissociates three times, into H 2 PO 4-, HPO 4 2-and PO 4 3-.The pKa value is based on the Ka value, which is called the acid dissociation constant. It is also used as a phosphorylating agent, analytical reagent and in dental cements. /T1_0 1 Tf Dithionic acid (H2S2O6): The oxidation state of sulfur in this oxy acid is +5. 0 g (http://www.jbc.org/content/116/1/409.citation.full.h)Tj endstream <> Metaphosphoric acid is often used as a moisture- or water-absorbing reagent.

The sim­plest com­pound of a se­ries of phos­phoric acids is some­times called by its com­mon name, or­thophos­phoric acid, but more often called by its IUPAC name, sim­ply phos­phoric acid, by both non-tech­ni­cal peo­ple and even many chemists.
