SummaryThe objective of this experiment is to determine the total concentration of metal ions required to completely react with EDTA, or ethylene diamine tetra-acetate. The concentration determined will then be taken as the equivalent concentration of Ca2+ and Mg2+. Ca2+ will be analyzed separately in an additional titration after Mg(OH)2 has been precipitated from the solution using a strong base.
