Cobalt(II) is stable in aqueous solution...

Cobalt(II) is stable in aqueous solution but in the presence of complexing reagents, it is easily oxidised. Explain.

Text Solution

Verified by Experts

Co(III) has greater ionic charge than Co(II). So Co(III) has greater tendency to form coordination complexes than Co(II). So in presence of ligands, Co(II) changes to Co(III) i.e., it is easily oxidised.
