1. Why do the preliminary tests not help in the identification of nitrate ion? 2. A student analyzes a sample using the preliminary tests and finds that no precipitate is obtained upon the addition of silver ion but a precipitate is observed on the addition of barium ion. Which individual ion tests should be used to determine the anions present in this sample? 3. In the preliminary tests 3 M HNO, is added to the precipitate of the silver group. If a yellow precipitate remains, what ion is probably present? 4. Why can't a fresh sample of unknown solution be used for the individual ion test for sulfite?

The procedures and principles of qualitative analysis are coy cred in many introductory chemistry laboratory courses. In qualitative analysis, students learn to analyze mixtures of the common positive and negative ions, separating and confirming the presence of the particular ions in the mixture. One of the first steps in such an analysis is to treat the mixture with hydrochloric acid, which precipitates and removes silver ion, lead(II) ion, and mercury(I) ion from the aqueous mixture as the insoluble chloride salts. Write balanced net ionic equations for the precipitation reactions of these three cations with chloride ion.
One method for determining the purity of aspirin (C9H8O4) is to hydrolyze it with NaOH solution and then to titrate the remaining NaOH. The reaction of aspirin with NaOH is as follows: A sample of aspirin with a mass of 1.427 g was boiled in 50.00 mL of 0.500 M NaOH. After the solution was cooled, it took 31.92 mL of 0.289 M HCl to titrate the excess NaOH. Calculate the purity of the aspirin. What indicator should be used for this titration? Why?
