Formula of lead acetate

Reflection The hair color solution I have the students analyze is Grecian Formula 16. The solution contains elemental sulfur, which needs to be filtered off prior to the analysis. I usually do this before the laboratory procedure and save the filter paper to show the students and explain why this filtration is necessary. After the first year I did this lab, I wrote the company and asked if they would share with me the actual percentage of lead (II) acetate. They indicated in their response that the product contained between 0.29 and 0.34% lead (II) acetate by weight. Because of the small amount of lead (II) acetate present, a balance capable of massing to 0.001 grams is necessary. The profit margin calculation is very crude because it assumes that the only cost of production is the cost of the chemicals. However, it does serve to give students some insight into what profit margins are and how they are determined. Final Note: Because of the expense of Grecian Formula 16, I usually buy one bottle, filter off the sulfur, and combine it with a 0.32% lead acetate solution that I mix up in the lab. One bottle is purchased so that the solution to be analyzed will have the correct properties, namely odor. Both procedures have their advantages and disadvantages. I have found that Procedure I works the best. Procedure I • Measure out about 10 cc of hair color product. Be sure to record the exact volume used. The exact mass of the solution will also be needed. This will require the m...

There are many types of quantitative techniques that are based on stoichometry, and many of these deal with solutions, and will be covered in the next several sections of this Chapter Gravimetric Analysis: The identification of the quantity of an unknown solute in a solution by making it the limiting reagent of precipitation reaction, weighing the mass of the resulting...
