Complexometric Determination of Water Hardness. Abstract: Using complexometric method of calculating water hardness‚ an EDTA solution was made and calculated to be around .00209M. This EDTA solution was then used to titrate a water sample with unknown hardness. The sample used was sample #18. The hardness of the sample was calculated to be 180505 ppm. This is within normal levels for the Mesa area. Introduction: This experiment focuses on titration with EDTA. Titration
