How many EDTA (ethylenediaminetetraacetic acid) molecules are required...
Octahedral Complex with Ca2+ Ion using EDTA Molecules
To form an octahedral complex with a Ca2+ ion, only one EDTA (ethylenediaminetetraacetic acid) molecule is required. This is because EDTA has a hexadentate ligand, meaning it can form six coordinate bonds with a metal ion.
Ethylenediaminetetraacetic Acid (EDTA)
- EDTA is a chelating agent that can form stable complexes with metal ions by surrounding the metal ion with multiple coordinate bonds.
- It has four carboxylic acid groups and two amine groups that can act as binding sites for metal ions.
Formation of Octahedral Complex
- In the case of Ca2+ ion, which has a coordination number of 6, one molecule of EDTA can form six coordinate bonds with the Ca2+ ion in an octahedral arrangement.
- The EDTA molecule will bind to the Ca2+ ion through its six available binding sites, forming a stable octahedral complex.
Conclusion
In conclusion, only one molecule of EDTA is required to form an octahedral complex with a Ca2+ ion due to the hexadentate nature of EDTA. This complexation process is widely used in analytical chemistry and biochemistry for the determination and chelation of metal ions.
