The calmagite color indicator is added to form weak complexes at this basic pH with magnesium and calcium, forming a red colored complex. Addition of the EDTA titrant solution also forms complexes with the remaining free magnesium and calcium ions. Once all of the free magnesium and calcium ions have been complexed, the excess EDTA preferentially removes the ions bound with the calmagite color indicator, forming a stronger complex. The removal of these metal ions from the indicator causes a color change from red to blue, indicating the endpoint of the titration.
