Question:

I need help creating a chemistry lab?

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.

Answer:

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.
