Calcium Analysis by EDTA Titration

In a titration to establish the concentration of a metal ion, the EDTA that is added coines quantitatively with the ion to form the complex. The end point occurs when essentially all of the ion has reacted. In this experiment you will standardize a solution of EDTA by titration against a standard solution made from calcium carbonate, CaCO3.
