MCQ
The coordination environment of $Ca ^{2+}$ ion in its complex with EDTA ${ }^{4-}$ is :
- Atetrahedral
- Boctahedral
- Csquare planar
- Dtrigonal prismatic
✓
Answer
[b]
EDTA $^{4-} \rightarrow$ Hexadentate ligand
$
[Ca(\text { EDTA })]^{2-}
$
So Coordination environment is octahedral
EDTA $^{4-} \rightarrow$ Hexadentate ligand
$
[Ca(\text { EDTA })]^{2-}
$
So Coordination environment is octahedral
