three hydronium ionsIt gives three hydronium ions in aqueous solution.
Acid property of H3PO3 Thus one hydrogen ion is formed. The obtained product hydrogen phosphite ion is a weak acid with a pKa value of 6.7. It will also donate one hydrogen ion to form a phosphite ion.
There are four hydrogen atoms in the molecule, but only the one hydrogen that is bonded to an oxygen atom is ionizable.

Phosphoric acid forms three classes of salts corresponding to replacement of one, two, or three hydrogen atoms.
In this compound, three hydrogen atomsS is joined with three oxygen atomsS. Therefore, the value of basicity is 3.
H3PO4Phosphoric acid / Formula
3H3PO4 3H+ + PO4- For hydrogen to be acidic it must be attached to strong electronegative atom. Here it is attached to 3 oxygen Hence basicity of H3PO4 is 3.
hydronium ionAs H+ ions are formed, they bond with H2O molecules in the solution to form H3O+ (the hydronium ion).Aug 15, 2020
For hydrogen to be acidic it must be attached to a strongly electronegative atom. It has two P−OH bonds and one P−H bond. Hence, its basicity is 2. Here it is attached to 2 oxygen Hence basicity of H3PO3 is 2.
three hydrogen atomsAcetic Acid Formula They are composed of three hydrogen atoms and one carbon atom (CH3). As carbon has four electrons, the free electron usually bonds with other molecules by way of a covalent bond.Oct 27, 2020
10) Vinegar pH =3 [H+] = 10-3 [H+] = 1x10-3 moldm-3 Detergent pH = 8 [H+] = 10-8 [H+] = 1x10-8 moldm-3 The vinegar has the higher [H+] by a factor of 100000.
Acetic acid belongs to a family of organic compounds known as carboxylic acids. It has one acidic proton attached to the oxygen.Jun 5, 2019
tribasic acidA tribasic acid contains three replaceable hydrogen atoms in a molecule. So, acids contain replaceable hydrogen.
To clarify this concept, consider the following acids: Hydrochloric acid (HCl) has one replaceable hydrogen ion (H+). Sulfuric acid (H2SO4) has two replaceable hydrogen ions (2H+)....AcidValence (Replaceable hydrogen ions)HNO3n = 1H2SO4n = 2HFn = 11 more row
