How many EDTA (ethylenediaminetetraacetate) unit(s) are required to make an octahedral complex with a Ca 2 + ion?

Options

  1. ASix
  2. BThree
  3. COne
  4. DTwo

Correct answer

C. One

Step-by-step solution

As EDTA is hexadentate ligand. Hence, only one EDTA (ethylenediamine tetraacetate) molecule is required to make an octahedral complex with Ca 2 + .
