A water sample was analyzed for the total hardness through the reaction between the sample and EDTA. The data obtained from the experiment are presented below (MM CaCO3 = 100.0869 g/mol): Table 1. Standrdization of the EDTA solution mass of CaCO3 used 0.4567 g Initial burette reading 8.20 mL Final burette reading 15.65 mL Volume consumed 7.45 mL Table 2. Determination of Hardness of Water Volume of water sample 50.00 mL Initial burette reading 15.65 mL Final burette reading 24.85 mL Volume consumed 9.20 mL 12,390 ppm 990 ppm 11,270 ppm O 10,290 ppm
