1. You have a solution that you believe contains either ANO, or Fe(NOX). Describe a test that will let you confirm which is present. Describe the test in detail, and include a chemi- cal equation. 2. Would any of the tests you have used let you determine if a solution contained the potas- sium ion, K+? Either identify a test, or explain in detail why such a test is not possible using the simple methods described here. 3. A sample...

Post-Lab Questions: 1. If you had a solution which contained only chloride, bromide, or iodide ion, which of the three tests would most clearly tell you which anion was in the solution? Explain. 2.) Suppose that you were quite sure that your unknown contained only sulfate ion. Which test would most quickly (that is, in the fewest steps) confirm your hypothesis? Explain. Consider each set of results below which were carried out on a solution containing either (1)one of the...

2. What will you observe when you have a positive test for: (a) bicarbonate anion(HCO3-)? • Bubbles Dobre lieT like gas o colorless (b) phosphate anion(PO43-)? 1. A student studied some reactions involving Pb2+ ion, copper(II) ion (Cu2+), and nickel(II)ion (Ni2+). The student first observed the behavior of individual solutions of Pb(NO3)2, copper(II) nitrate, Cu(NO3)2, nickel(II) nitrate, Ni(NO3)2, interacting individually with 1M HCl solution and then individually with 1M sodium hydroxide solution (NaOH). The student also added an aqueous ammonia...

Experiment 8 Name: Double Replacement Reactions Background: Some reactions have the net effect of causing the cation of cach reactant to trade places, forming a compound with the other anion. These reactions are known as double replacement reactions. In the example below (unbalanced equation), the barium and sodium cations switch places so that barium forms a product with sulfate while sodium forms...
