6. 20 mL of tap water sample is taken in a conical flask and 1 mL of pH 10 buffer and 3 drops of iochrome black-T indicator are added and when titrated with 0.001 M EDTA solutien, 16 mL EDTA is spent, so the hardness of the water is determined by French Hardness and German Hardness Calculate in terms.
