The coordination environment of \( \text{Ca}^{2+} \) ion in its complex with \( \text{EDTA}^{4-} \) is:
Updated On: July 22, 2025
- tetrahedral
- octahedral
- square planar
- trigonal prismatic
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
In the Ca$^{2+}$-EDTA complex, EDTA acts as a hexadentate ligand, coordinating through six donor atoms. This creates an octahedral geometry around Ca$^{2+}$.
