In a complexometric titration of metal ion with ligand M ( M e t a l i o n ) + L ( L i g a n d ) → C ( C o m p l e x ) end point is estimated spectrophotometrically (through light absorption). If 'M' and 'C' do not absorb light and only 'L' absorbs then the titration plot between absorbed light ( A ) versus volume of ligand 'L' ( V ) would look like:

Initially ligand consumed by metal due to formation of complex. So absorbed light ( A ) remain constant, after complex formation is completed, extra volume of ligand solution increases ligand concentration and also increases absorbed light.
