Magnesium is a vital mineral for humans, as it plays an important role in many processes in the body. The risk of magnesium deficiency is avoided by taking supplements containing magnesium in various forms. Magnesium levels can be determined by classical methods or by instrumental methods. In this work, I have focused on two methods, namely AAS or atomic absorption spectroscopy and complexometric titration. I have determined the Mg in seven samples and compared it with the reported value. I have also investigated whether both methods give comparable results. In the case of complexometric titration, I also performed a standardization of EDTA with zinc beforehand to determine the exact EDTA concentration.
