corrosion technologist pipetted a 100.00 mL hard water sample and titrated it with 37.64 mL of 0.01 M EDTA solution for a total hardness endpoint, and 29.32 mL of 0.01 M EDTA solution for a calcium endpoint. Calculate the concentration of magnesium and calcium in ppm. Record your answers as ppm Mg2+, and Ca2+ espectively. For each answer indicate the ppm as CaCO3 also.
