A student performs a spot test to identify the ions in an unknown solution. The student did a series of tests and found these results: adding HCI produced effervescence; acidification produced a vinegar odor; (NH4)2M004 plus HNO3 produces a yellow precipitate. Which one of the following is among the ions in the mixture? both b and c NH4+ SCN S04-2 co3-2 QUESTION 1o Which one of the following tests requires a heating process? Test for SOA-2 Test for CO3-2 Test for NH4+ both a and b QUESTION 11 A student performs a spot test to observe the ions in unknown solution. The mixture may contain CO22-, s04-2, PO4-3, SCN -, CI¯, C2H302¯, or NH4+. Wher student is doing the tests, interferences are a concern. Which of these interferences could cause a problem in this experiment? Chloride Interferes with the Phosphate Test Thiocyanate Interferes with the Carbonate Test Phosphate Interferes with the Carbonate Test Phosphate Interferes with the Thiocyanate Test

COMPLETE THE MECHANISM AND DRAW ATLEAST TWO FORMS FOR THE WHELAND INTERMEDIATE.
Part A - Solution 1 After being given a solution containing a set of unknown ions, you perform the following sequence of tests to determine the identity of the cations in solution: 1. A flame test produces no color 2. You take a small portion of the solution and add NaOH. A vapor is produced that turns red litmus blue. 3. You add HCI to solution, which results in the formation of a white precipitate. The supernatant is separated and used for the remainder of the tests. 4. The addition of buffered NH4*/NH3 to a portion of the supernatant from step 3 does not produce a precipitate. 5. The addition of ammonium oxalate to a portion of the superntant from step 3 does not produce a precipitate 6. The addition of a strong base to a portion of the supernatant from step 3 generates a precipitate. 7. The supernatant from step 6 is separated from the precipitate. The addition of HCI and K4Fe(CN)6 to the solution produces no reaction. Based on these tests, identify which of the following ions must…
