The volume of EDTA consumed (V1 mL) is used to calculate the hardness of the given sample in mg/L of CaCO3 as follows: 1000 ppm CaCO3 equivalent in standard hard water = 1 mg/mL 1 mg/mL requires V1 mL of EDTA for titration x mg/mL in sample will require V1 mL of EDTA 1000 x = V1 x x = 1000 x V1/20 Hardness of sample in mg/L of CaCO3 = 1000 x V1/20 Titration-II: Estimation of hardness in given water sample Take 20 mL of the given water sample in a clean conical flask.
