Advance Study Assignment: Spot Tests for Some Common Anions
An unknown containing one or more of the ions studied in this experiment has the following properties:a. No effect on addition of 6 M HNO3.b. No effect on addition of 0.1 M AgNO3 to solution in Part A.c. White precipitate on addition of 1 M BaCl2 to solution in Part A.d. Yellow precipitate on addion of (NH4)2MoO4, to solution in Part A.On the basis of this information which ions are present, which are absent,and which are in doubt?

3. A solution that may contain any of the group III cations. Treatment of the solution with CIO in alkaline medium yields a yellow solution and a colored precipitate. The acidified solution is unaffected by treatment with NH,OH. The colored precipitate dissolves in nitric acid; addition of excess NH,OH to this acidic solution produces only a blue solution. Which group III ions are present? Which are absent? Which are in doubt? How would you remove all doubt?

Each of the observations listed was made on a different solution. Given the observation, state which ion studied in this experiment is present. If the test is not definitive, indicate that with a question mark. a. Addition of 6 M NaOH and Al to the solution produces a vapor that turns red litmus blue. Ion present: b. Addition of 6 M HCI produces a vapor with an acrid odor. Ion present: c. Addition of 6 M HNO_3 produces an effervescence....

2. A solution that may contain Sn.Bi. Cu? and Cdions is treated with thioacetamide in an acidic medium. The black precipitate that forms is partly soluble in a strongly alkaline solution. The precipitate that remains is soluble in 6M HNO, and gives a blue solution when treated with excess NH Based on this information, which ions are present, which are absent, and which are still in doubt?
