Chemical Reaction of Solution Lab Report
CHEMICAL REACTIONS OF COPPER AND PERCENT YIELD
Objective
To gain familiarity with basic laboratory procedures, some chemistry of a typical transition element, and the concept of percent yield.
Apparatus and Chemicals
|0.5 g piece of no. 16 or no. 18 copper wire |evaporating dish |
|250 mL beaker (2) |weighing paper |
|concentrated HNO3 (4 – 6 mL) |6.0 M H2SO4 (15 mL) |
|graduated cylinder |granular zinc |
|3.0 M NaOH (30 mL) |methanol |
|carborundum boiling chips |acetone |
|stirring rod |towel |
|iron ring and ring stand |balance |
|wire gauze |aluminum foil cut in 1-inch squares |
|Bunsen burner |concentrated HCl (drops) |
Discussion
Most chemical synthesis involves separation and purification of the desired product from unwanted side products. Some methods of separation, such as filtration, sedimentation, decantation, extraction, and sublimation were discussed earlier. This experiment is designed as a quantitative evaluation of your individual laboratory skills in carrying out some of these operations. At the same time you will become more acquainted with two fundamental types of chemical reactions -- redox reactions and metathesis (double-displacement) reactions. By means of these reactions, you
