Phosphoric acid, also known as orthophosphoric acid or phosphoric(V) acid, is a weak acid with the chemical formula H
₃PO
₄. The pure compound is a colorless solid.
All three hydrogens are acidic to varying degrees and can be lost from the molecule as H⁺ ions.
Which is orthophosphoric acid?
Phosphoric Acid is a weak acid with chemical formula H3PO4. Phosphoric Acid is an acid-containing four atoms of oxygen, one atom of phosphorus, and three atoms of hydrogen. It is also known as phosphoric(V) acid or orthophosphoric acid. It is present in teeth and bone and helps in metabolic processes.
What is the N factor of orthophosphoric acid?
Orthophosphoric acid is a tribasic acid; it has three replaceable hydrogen ions per mole. For acids n-factor is basicity it is defined by the number of hydrogen ions replaced. n-factor for orthophosphoric acid is 3.
How do you calculate n Factor?
To calculate n-factor of a salt of such type, we take one mole of the reactant and find the number of mole of the element whose oxidation state is changing. This is multiplied with the oxidation state of the element in the reactant, which gives us the total oxidation state of the element in the reactant.
What is the N factor of H 3 PO 4?
of H+ ions it produces on dissociation per molecule of acid is 3. Hence the n-factor for phosphoric acid H3PO4 is 3.

What is the equivalent weight of H 3 PO 4?
The molecular weight of phosphoric acid is; (3+31+16*4)gram/mol = 98 gram/mol. Now Equivalent Weight = 98/3 gram/equivalent = 32.67 gram/equivalents.
What are the N factor of H 3 PO 3 and 3 Po 3 respectively?
Phosphorus acid has a basicity of 2. This is because H3PO3 can donate two OH – ions or it contains 2 replaceable H + ions. So, the normality of the given phosphorus acid is 0.6 N.

Is H2PO4 a base or acid?
Salts containing the anion H2PO4‾ are weakly acidic. The tendency of this ion to dissociate is greater than its tendency to hydrolyse, that is, its Ka2, is larger than its Kb. Because H2PO4‾ is weakly acidic and of low toxicity, it is used as the acid in some baking powders.
