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 5.5Γ10β2m in calcium chloride and 8.0Γ10β2m in magnesium nitrate.
what mass of sodium phosphate must be added to 1.5l of this solution to completely eliminate the hard water ions? assume complete reaction.
