Edta calcium magnesium

The combined concentration of calcium and magnesium ions is considered to be the measure of water hardness. The method uses a very large molecule called EDTA which forms a complex with calcium and magnesium ions. EDTA is short for ethylenediaminetetraacetic acid. chemistry quantitative analysis lab webnote edta titration for determination of calcium and magnesium before attempting this experiment.
