HA + H2O H3O + + A-If Ka < 10-3 and both [HA] init and [A-] init are > 10-3 M, then [HA] eq [HA]init and [A-] eq [A-] init. How does each acid ionise in water? It is a triprotic acid, meaning it can donate 3 hydrogen ions successively with each reaction (we'll explore more into this as we go) and is a relatively weak acid since its degree of ionisation is not 100% ie. The net charge on the left side of the equation must reflect this net charge. There is no need to go the lengthy quadratic route for [H3PO4] use 5.0 M . Our techniques for working diprotic acid or diprotic base equilibrium problems can be applied to triprotic acids and bases as well.

Ba(OH)2 c. HClO d. KOH. The values of dissociation constants of some acids (at 25 0C) are as follows. If b > a, then the resulting solution is basic. The pKa value measures the acidity of a solution based on how the hydrogen ions of the acid dissociate when added to an aqueous solution. 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. Phosphoric acid is a weak acid which only partially ionizes during dissociation.H 3 PO 4 can donate three protons during dissociation reaction H 3 PO 4 has three steps of dissociation. First week only $4.99! Similarly in case of H 3P O3 gives two products on diproportionation on heating. H3PO2 (aq) is a weak monoprotic acid which dissociates partially, this means that it does not donate all of its hydrogen ions (H+) in a solution.
