UNKNOWN SAMPLE #97 COMPLEXOMETRIC DETERMINATION OF WATER HARDNESS DR. BUDRUK CHM 152 LL SEAN MARKIS 4 FEBRUARY 2015 Introduction Using a Lewis base neutral molecule to donate electron pairs (ligands) to a Lewis acid metal ion center to form a single cluster (complex) ion. When the complex ions forms with a metal ion (chelation) the ligand used is called the (chelating agent). EDTA acts as a great chelating agent due to the Nitrogen and Oxygen donating an electron pair to the
