Hard water habitually contains dissolved Ca2+ and Mg2+ ions. One means to soften water is to add phosphates. The phosphate ion forms inexplicable precipitates with calcium as well as magnesium ions removing them from solution. Assume that a solution is 5.0 x 10(-2) M in calcium chloride also 9.5 x 10(-2) M in magnesium nitrate.

Explain what mass of sodium phosphate would have to be added to 1.0 L of this solution to completely eradicate the hard water ions? Presume complete reaction.
