Purpose:
The purpose of this lab is to establish a concrete understanding of limiting reagents and percent yields. In addition, the lab should give the administrator the ability to analyze the effects of reactants on the product of a chemical reaction.
Procedure:
In part A of the lab, the first step in the procedure is to add 20 mL, and 25 mL of CaCl2 to two different flasks. Following this, the administrator is to add 10 mL of Na2CO3 to the flask containing 20 mL of CaCl2, and 5 mL of the same solution to the flask containing 25 mL of CaCl2. While the administrator is waiting for the precipitate to form from the two mixtures, they should determine if there was a limiting reagent. When these solutions have formed a precipitate, they are to …show more content…
They will then attain five small test tubes, in which they will mix varying amounts of copper sulfate and sodium hydroxide. Once a precipitate has formed in all five test tubes they will record and analyze their observations.
Fun Fact:
The technique used to determine the limiting reagent in part A of this lab, is used to determine how much of a desired product can be produced, which is tremendously important in the medical field. An example of such a situation is the chemical is benzoyl peroxide. This chemical is common in acne medication, and helps fights acne via its oxidizing properties. Thus, the amount of benzoyl peroxide that is produced is crucial to the effectiveness of the acne medicine it is within.
Safety:
The acids and bases used throughout this lab are corrosive, thus all contact with skin should be avoided. if there is any skin to acid or base contact, the body part should be washed immediately. All the solutions used in this lab should be disposed of as hazardous waste. And finally, as always proper lab attire, apron, and glasses are required once inside of the laboratory.
