Explanation of the Formula
- C₂: 2 carbon atoms.
- H₈: 8 hydrogen atoms.
- O₇: 7 oxygen atoms.
- P₂: 2 phosphorus atoms.
Structural Formula
This structure shows:
- A central hydroxyethylidene group (CH3C(OH)).
- Two phosphonate groups (PO3H2) attached to the central carbon.
Key Features of the Structure
- The phosphonate groups (PO3H2) are responsible for HEDP’s strong chelating ability.
- The hydroxy group (OH) and methyl group (CH3) provide stability to the molecule.
