Strontium, Sr2+, is a heavy metal that frequently causes concern when it is present in water. Some preliminary calculations are necessary to determine whether it is feasible to precipitate Sr2+ as the sulfate. Given that 10-4 mole/L of Sr2+ and 10-4 of SO4 2- are originally present and that pkso = 7.8 for SrSO4(s). How much Sr2+ will precipitate (moles/L) if 0.4 X 10-3 mole Na2SO4 is added per liter of solution? How much SO4 2- and Sr2+ remain after precipitation?
