Acidic properties of O-Phosphoric acid:
All three hydrogens are acidic, with dissociation constants pKa1 = 2.14, pKa2 = 7.20, and pKa3 = 12.37.
O-Phosphoric acid follows that, in water solutions, phosphoric acid is mostly dissociated into some combination of its three anions, except at very low pH.
The equilibrium equations are:
H3PO4 + H2O ⇌ H3O+ + H2PO4−
Ka1= 7.25×10−3 [pKa1 = 2.14]
H2PO4−+ H2O ⇌ H3O+ + HPO42−
Ka2= 6.31×10−8 [pKa2 = 7.20]
HPO42−+ H2O ⇌ H3O+ + PO43−
Ka3= 3.98×10−13 [pKa3 = 12.37]
Removal of one or two protons gives dihydrogen phosphate ion (H2PO−)4, and the hydrogen phosphate ion (HPO2−)4, respectively.
O-Phosphoric acid forms esters, called organophosphates.
The name "O-Phosphoric acid" can be used to distinguish this specific acid from other "phosphoric acids", such as pyrophosphoric acid.

PRODUCTION of O-Phosphoric acid:
O-Phosphoric acid is produced industrially by one of two routes, wet processes and dry.
O-Phosphoric acid may be obtained by adding sulphuric acid to the phosphate of baryta suspended in water.
The sulphuric acid unites with the baryta forming an insoluble salt which precipitates while the phosphoric acid remains in solution.
When phosphorus is gradually added to nitric acid, O-Phosphoric acid is generated and remains mingled with the residual nitric acid
-Wet process:
In the wet process, a phosphate-containing mineral such as calcium hydroxyapatite and fluorapatite are treated with sulfuric acid.
Ca5(PO4)3OH + 5 H2SO4 → 3 H3PO4 + 5 CaSO4 + H2O
Ca5(PO4)3F + 5 H2SO4 → 3 H3PO4 + 5 CaSO4 + HF
Calcium sulfate (gypsum, CaSO4) is a by-product, which is removed as phosphogypsum.
The hydrogen fluoride (HF) gas is streamed into a wet (water) scrubber producing hydrofluoric acid.
In both cases the O-Phosphoric acid solution usually contains 23–33% P2O5 (32–46% H3PO4).
It may be concentrated to produce commercial- or merchant-grade O-Phosphoric acid, which contains about 54–62% P2O5 (75–85% H3PO4).
Further removal of water yields superphosphoric acid with a P2O5 concentration above 70% (corresponding to nearly 100% H3PO4).
The O-Phosphoric acid from both processes may be further purified by removing compounds of arsenic and other potentially toxic impurities.
-Dry process:
To produce food-grade phosphoric acid, phosphate ore is first reduced with coke in an electric arc furnace, to give elemental phosphorus.
Silica is also added, resulting in the production of calcium silicate slag.
Elemental phosphorus is distilled out of the furnace and burned with air to produce high-purity phosphorus pentoxide, which is dissolved in water to make O-Phosphoric acid.
O-Phosphoric acid can be conveniently prepared by dissolving P2O5 in water followed by boiling the solution to form a thick syrup.
P2O5 + 3H2O → 2H2PO4
Red phosphorus when heated with conc.HNO3 yields O-Phosphoric acid.
P + 5HNO3 → H3PO4 + H2O + 5NO2
On a large scale, it is prepared by treating phosphorite rock with dil.H2SO4.
Ca3(PO4)2 + 3H2SO4 → 3CaSO4 + 2H3PO4

CHEMICAL PROPERTIES of O-Phosphoric acid (H3PO4):
O-Phosphoric acid is a deliquescent solid, generally encountered as a viscous aqueous solution.
O-Phosphoric acid is weakly acidic, with three possible sequential deprotonation steps, forming phosphates.
Like carboxylic acids, O-Phosphoric acid can dimerize via a dehydration reaction to form phospho anhydrides.
O-Phosphoric acid is referred to as being tribasic, in that it has three possible dissociation steps.
As a result mono and disodium and potassium salts of O-Phosphoric acid are routinely used as pH buffers.
One of the most important reactions of O-Phosphoric acid and its derivatives is multimerization.
As with carboxylic acids, two O-Phosphoric acid molecules may combine with the loss of water to form a di phosphate ester also referred to as pyrophosphate.
However, as O-Phosphoric acid has further -OH functionalities triphosphates may also be formed.
Salts of O-Phosphoric acid are solid and many are relatively water-insoluble unless a strong mineral acid is present.

BASICITY OF O-Phosphoric acid (H3PO4):
The basicity of acids is represented by the number of hydrogen atoms which can be replaced by electro – positive atoms.
Basicity of an acid is the number of hydrogen ions that can be produced by the ionization of one molecule of the acid in its aqueous solution.
An acid which produces three hydrogen or hydronium ions by the ionization of one molecule of the acid, is called a tribasic acid or tri protic acid.
For example, O-Phosphoric acid and H3PO3 are tribasic acids.
SAFETY:
Although O-Phosphoric acid is not a strong acid, solutions can irritate the skin and damage the eyes.
A link has been shown between long-term regular cola intake and osteoporosis in later middle age in women (but not men).
At moderate concentrations O-Phosphoric acid solutions are irritating to the skin.
Contact with concentrated solutions of O-Phosphoric acid can cause severe skin burns and permanent eye damage.
