						I have to test a solution that may contain any or all of the nitrate salts of Mg²⁺, Sr²⁺, Ca²⁺ and Ba²⁺. Because I cannot use a flame test, I'll have to test the solution by observing the percipitates formed (if any) when H₂SO₄, NaOH, (NH₄)₂C₂O₄ or K₂CrO₄ reacts with the above nitrate salts. It has been experimentally shown that the nitrate salt of Sr²⁺ forms a precipitate aqueous solutions containing SO₄^2-, C₂O₄^2-, and CrO₄^2- compounds. The nitrate salt of Mg²⁺ forms a percipitate with only the OH^- compound. The Nitrate Salt of Ca²⁺ forms a percipitate with OH^- and C₂O₂^2-. Finally, Ba²⁺ forms precipitates with everything Sr²⁺ reacts with. Since the Stronium and Barium react with the same compound, something else must be done. I have the following materials: All the compounds above in Aqueous form. Acetic Acid Microcentrifuge Nitric Acid Distilled Water Test tubes, beakers, and flasks. I'm not able to create an accurate flow-chart that could test for all or any of the nitrate salts. Please help.
