COMPLEXOMETRIC TITRATION A deep well sample of 100 mL was titrated with 0.010 M EDTA at pH=10 (with Mg-EDTA-PH10 reagent) and consumed 31.95 mL using EBT indicator. Titration of another 100 mL of the same deep well sample with the same titrant but the pH was adjusted to 12.10 and murrexide as indicator consumed 24.25 ml to reach end point. Calculate: А. Total Hardness of water as CaCO3 В. ppm of Ca and Mg 76
