Hard water often contains dissolved calcium ion and magnesium ions. One way to soften water is to add phosphate salts. The phosphate ion forms insoluble precipitates with calcium and magnesium ions, removing them from solution. Suppose that a solution is 5.5×10−2 M in calcium chloride and 9.5×10−2 M in magnesium nitrate. What mass of sodium phosphate would have to be added to 11.5 L of this solution to completely eliminate the hard water ions? (Assume complete reaction.)
