Hard water often contains dissolved ca2+ and mg2+ ions. one way to soften water is to add phosphates. the phosphate ion forms insoluble precipitates with calcium and magnesium ions, removing them from solution. suppose that a solution is 5.0×10−2 m in calcium chloride and 8.5×10−2 m in magnesium nitrate. what mass of sodium phosphate would have to be added to 2.0 l of this solution to completely eliminate the hard water ions? assume complete reaction.
