A 1,000-mL solution contains 5.55 g of CaCI, and 4.77 g of MgCl2. a. How many milliliters of 0.02 N standard versenate solution would be required in the API titration for total hardness? Answer: 10 mL per 1-mL sample. b. Express the concentrations of Ca2+ and Mg+ in parts per million. Answer: 5,550 and 4,770 (approximate for p,=Pw).
