Complexometric titration of zn(ii) with edta must be turned in at least 1 lab period before you plan to do the experiment so that ml of deionized water, 9-10 . Complexometric titration is one of the best ways of measuring total water hardness at ph around 10 edta easily reacts with both calcium and magnesium in the same molar ratio (1:1) stability constant of calcium complex is a little bit higher, so calcium reacts first, magnesium later. Calcium analysis by edta titration you will then use the edta solution to determine the hardness of an unknown water sample use in next weeks aa experiment 3 .
Determination of water hardness by: diane krehbiel abstract: in this experiment, the hardness of an unknown water sample will be determined the calcium in the water will be measured by performing a titration with edta. The purpose of this experiment was to determine the concentration of metal ion impurities in an unknown sample of hard water by performing a complexometric titration with edta the results were then compared to the expected range for municipal water hardness from multiple city websites.
