assuming that an insoluble salt will form when aqueous solutions of the follow

Experiment 11 Pre-Lab Questions Section: Name an insoluble salt (precipitate) will form when aqucous (water) solutions of Assuming that the following cations and anions are mixed, write the formula of the salt Barium + chromate Calcium + oxalate Magnesium+ carbonate Strontium +sulfate cations A. B, C, and D were mixed with solutions containing So lutions containing anions W. X and Z. Precipitates formed as indicated 2. ppt Ppt pp ppt ppt ppt c* Dt ppt ppt An unknown solution contains only one of the cations. Outline a procedure using only two anion solutions for its identification. Hint: Start with an a with 2 cations and is soluble with 2 cations. nion that forms precipitates 85
