What is the Difference Between Ortho Pyro and Meta Phosphoric Acid?
🆚 Go to Comparative Table 🆚The main difference between ortho pyro and meta phosphoric acid lies in the number of phosphoric acid units and their structure. Here are the key differences:
- Ortho Phosphoric Acid:
- Contains one phosphoric acid unit.
- Chemical formula: H3PO4.
- Weak mineral acid.
- Non-toxic and important for plants as a major source of phosphorous.
- Molar mass: 97.99 g/mol.
- Pyro Phosphoric Acid:
- Contains two phosphoric acid units, linked together by a single oxygen atom.
- Chemical formula: H4P2O7.
- Stronger acid than ortho phosphoric acid.
- Meta Phosphoric Acid:
- Contains more than two phosphoric acid units, linked in a linear chain.
- Chemical formula: HPO3.
- Stronger acid than ortho and pyro phosphoric acids.
In summary, ortho phosphoric acid is a single phosphate unit, pyro phosphoric acid contains two phosphate units linked together, and meta phosphoric acid has more than two phosphate units linked in a linear chain. Ortho phosphoric acid is the weakest of the three, while pyro and meta phosphoric acids are stronger acids.
Comparative Table: Ortho Pyro vs Meta Phosphoric Acid
The difference between ortho pyro and meta phosphoric acid can be summarized in the following table:
Property | Ortho Phosphoric Acid | Pyro Phosphoric Acid | Meta Phosphoric Acid |
---|---|---|---|
Chemical Formula | H3PO4 | H4P2O7 | HPO3(n) |
Number of Phosphoric Acid Units | 1 | 2 | n (3 or more) |
Molar Mass | 97.99 g/mol | - | - |
Oxidation State of Phosphorus | +5 | +5 | +5 |
Structure | Single phosphorus-oxygen tetrahedron | Linear structure with two phosphoric acid units | Cyclic structure with three or more phosphoric acid units bonded in a ring |
Ortho phosphoric acid, also known as phosphoric acid or orthophosphoric acid, is a weak inorganic acid with the chemical formula H3PO4. It is a non-toxic acid and is an important source of phosphorous for plants. Pyro phosphoric acid, with the chemical formula H4P2O7, has two phosphoric acid units and is a salt formed from pyrophosphoric acid. Meta phosphoric acid, with the general formula HPO3(n), has cyclic structures with three or more phosphoric acid units bonded in a ring, and its simplest compound is trimetaphosphoric acid (H3P3O9).
