What Is The Mass Percent?
A sample weighing 14.98g and containing a small amount of copper was treated to give a solution containing aqueous Cu^2+ ions. Sodium iodide was then added ti yield solid copper (I) iodide plus I3^- ion, and the I3^- was titrated with thiosulfate, S2O3^2-. The titration required 10.49mL of .100M Na2S2O3 for complete reaction. What is the mass percent copper in the sample? The balanced equations are…
