I need to preform experiments that provide a strong (or clearly obvious) visual conformation test for the existence of the following:a complexation reactiona replacement reactionamphoterismexistence of a common gaspercipitatei also need to design a test to illustrate the difference between acid and base catalyzed redox of H2O2 including a test for the presence of any gases generated.I have a lot of the common lab chemical regents available to meIf you can help in any way shape or form possible, it will be much appreciated.
Assuming that you already have some of the stuff and aren't going for top of the line, then about $300 to $500Also don't forget about your bugout vehicle (if it's neccesary to your plan)Have you watched Preppers?
Complexation: Prepare a dilute solution of CuSO4 in water, maybe 0.1M or 0.01MAdd ammonium hydroxide slowlyFirst, a light blue precipitate of cupric hydroxide, Cu(OH)2(2), formsThis dissolves to form an electric blue solution of tetramminecopper(II)Replacement: Dip a strip of zinc in the copper sulfate solution used aboveAn orangey-red coating appears on the zincCu2+ + Zn Zn2+ + CuAmphoterism: Dissolve aluminum foil in some warm, dilute HCl solutionAdd strong NaOH solution to the resulting AlCl3(aq) solution until Al(OH)3(s) forms and goes on to form Na+ Al(OH)4- solutionGas: Combine vinegar (5% acetic acid in water) with baking soda, NaHCO3, and watch the common gas, CO2, evolvePrecipitate: The Cu(OH)2 and Al(OH)3 prepared above are good examples of precipitatesH2O2: I don't know about acid and base catalysis, but if you could catch the oxygen gas formed under water and demonstrate its presence by causing a glowing splint to burst into flame, that would be the test.
