Answer :
Based on the potential ligands given, C2O42- and CO32- can form a maximum of two bonds to a metal
ion.
What are ligands?
Ligands are ion or molecule that binds to a central metal atom to form a coordination complex.
Ligands are essential in many biological and enzyme complexes.
From the potential ligands given;
- C2O42- can form can form a maximum of two bonds to a metal ion
- CO32- can form two a maximum of two bonds to a metal ion
- EDTA can form five to six bonds to a metal ion
- Porphine can form one bond to a metal ion
Therefore, the potential ligands, C2O42- and CO32- can form a maximum of two bonds to a metal
ion.
