Textbook Question
Chapter 28, Problem 3ASA
A 100-mL sample of hard water is titrated with the EDTA solution in Problem 2. The same amount of Mg2+ is added as previously, and the volume of EDTA required is 31.84 mL.
a. What volume of EDTA is used in titrating the Ca2+ in the hard water? _____________mL
b. How many moles of EDTA are there in that volume? _____________ moles
c. How many moles of Ca2+ are there in the 100 mL of water? _____________ moles
d. If the Ca2+ comes from CaCO3, how many moles of CaCO3 are there in one liter of the water? How many grams of CaCO3 are present per liter of the water? _____________ mol / L _____________ g / L
e. If 1 ppm CaCO3 = 1 mg per liter, what is the water hardness in ppm CaCO3? _____________ ppm CaCO3
