Advance Study Assignment: Spot Tests for Some Common Anions
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.

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....

A solution that may contain Cu2+, Bi3+, Sn4+, or Sb3+ ions is treated with thioacetamide in an acid medium. The black precipitate that forms is partly soluble in strongly basic solution. The precipitate that remains is soluble in 6 M HNO3 and gives only a white precipitate upon the addition of NH4OH. The basic solution, when acidified, produces, an orange precipitate.. which group 2 ions are present? which are absent? and which are still in doubt? How would you remove...

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?
