Extraction and Evaporation. Separating the Components of “Panacetin”

And finally into test tube 3, I pipetted 1.0 ml turnip extract and 4.0 ml of water. The contents of test tube 1 was poured into a spectrometer tube and labeled it “B” for blank. “B” tube was now inserted it into the spectrometer. An adjustment to the control knob was made to zero the absorbance reading on the spectrometer since one cannot continue the experiment if the spectrometer is not zeroed. A combination of two people and a stop watch was now needed to not only record the time of the reaction, but to mix the reagents in a precise and accurate manner. As my partner recorded the time, I quickly poured tube 3 into tube 2. I then poured tube 2 into the experiment spectrometer tube labeled “E” and inserted it into the spectrometer. A partner then recorded the absorbance reading for every 20 seconds for a total of 120 seconds. After the experiment, a brown color in the tube should be observed to indicate the reaction was carried out. Using sterile techniques, any excess liquid left was disposed

Panacetin is an analgesic (pain reducing) and antipyretic (fever reducing) drug that is sold in drug stores. However, there is a suspicion that this bottle may be counterfeit, not containing the chemicals that it should. Panacetin should be made up of about 50 percent of the unknown component that we previously separated out of Panacetin for testing. We suspect that this unknown compound is either acetanilide or phenacetin, both of which can be toxic to humans. It is very important that this component is

The purpose of this lab is to investigate the composition of a compound suspected to be Panacetin, a type of pain-killer. Panacetin is typically made up of sucrose, aspirin, and acetaminophen, but the third component in this experiment is unknown. The unknown component is suspected to be a chemical relative of acetaminophen, either acetanilide or phenacetin. Using techniques such as extraction, evaporation, and filtration, the three components will be isolated based on their solubilities and acid-base properties. Then, the percent composition of Panacetin can be deduced based on the masses of the three dried components. The

Sucrose is known to be insoluble in organic solvents such as dichloromethane (DCM) while Aspirin is soluble in DCM. Primarily, sucrose was removed so that it can be separated easily from the functioning ingredients that were present in Panacetin. Given that sucrose would not be able to dissolve if Panacetin was directly dissolved in the DCM. Aspirin however, is insoluble in water but it is known to contain a carboxylic acid group so it then will be able to react with sodium bicarbonate that is why the aspirin was recovered by reacting the conjugate base with hydrochloric acid. Finally, both Acetanilide and Phenacetin did not consist of an acidic hydrogen so instead they did not react with

This means that the amounts of acid and antacids may not have been equal for each trial. The size of the drops of acid and antacid could have been different. There are many ways that every experiment could be improved. One way would be to have two name brand antacids and two generic antacids. This would've helped us to figure out whether or not generic brands were better than name brands. Another way to improve the experiment would be to use larger amounts of the hydrochloric acid for each trial. Although it would be more expensive, the experiment would be more realistic to what people go through when they get heartburn. Also, using smaller amounts makes it harder to define whether or not the data is accurate. Since the units are smaller, it is a bigger difference when the data is inconsistent. The information gathered from this lab can easily be applied to the real world. Looking at the data, Rite Aid’s antacid was only effective when you used the same amount of acid as antacid. CVS and Gaviscon’s antacid only needed half of the amount of acid to neutralize. Rite Aid’s antacid wouldn't be useful for consumers with lots of stomach acid/

“How does taking a pill heal the pain in my legs?” 7-year old me thought. “How do the properties of specific drugs determine their function in the body?” 15-year old me thought. I have always been curious about how medicines work, and this curiosity leads me to search up practically everything I want to learn about. In my free time, instead of watching TV or reading mystery stories, I would scroll through “The Pharmaceutical Journal”, reading about studies that intrigue me.

Introduction: In this lab I had found out the process of making aspirin through synthesis and recrystallization. However, knowing how to make it and knowing how it is used in society are two different things. Everyone knows that aspirin is used for pain

To start our experiment, we created our control that was filled with water heated to sixty degrees Fahrenheit, then added a yeast packet to the water and mixed the solution. Next, we acquired one mole of sucrose, glucose, and fructose. The independent variables in our experiment included sucrose, glucose, and fructose, while the

The experiment began by filling the small beaker with 4 pipettes of both cooked starch and the amylase, and then transferring 4 pipettes of the mixed solution in a dialysis tubing bag. The large beaker was filled with water and 4 pipettes of Lugol’s solution before the dialysis bag was placed. The student then set up a control bag that contained only starch and placed it in a beaker containing only water and Lugol’s. The bags were placed in the beakers for one hour, and then the student used glucose strips to analyze the bag with the starch and amylase along with the fluid surrounding the bag in the

This series of labs aimed to synthesize and characterize aspirin from salicylic acid and acetic anhydride. The synthesis and recrystallization procedures entail the production and purification of aspirin. Several characterization techniques utilized in order to test its purity. Methods to characterize purity include determining the melting point of pure and crude aspirin, the pH

The purpose of this lab was to determine the composition of four different over-the-counter drugs (Anacin, Bufferin, Excedrin, and Tylenol). These compositions were determined by using the method of thin-layer chromatography (TLC) of the four over-the-counter drugs, which were then compared to four different components of drugs (acetaminophen, aspirin, caffeine, and salicylamide).

Clinicians and patients recognize the tremendous importance of medications in today 's medical care. Associated with the development of the pharmaceutical industry, its consumption has been increasing, and with it, the possibility of unwanted effects or adverse reactions.

Bag #4 had a 40% solution of sucrose and was red. Bag #5 was half filled with pure water with no coloring. Bags 1-5, where all half full with the described solutions, then tied close. Also, another two bags (bag #6 and #7), one containing water (bag #7) and bag #6 with 40% sucrose solution with red food coloring, are completely filled when tied, unlike bags #1-5. The dialysis tubes where knotted at both ends with a simple knot and tested to ensure no leaks, then a 6 inch long string was tied to one end of the bags to aid in retrieval from the beakers. One beaker was filled with enough water to cover all 5 half full bags (bags 1-5), whereas the other was filled with enough 40% sucrose solution to emerge the 2 full bags (bags 6 & 7). Please note that a control bag was present in both beakers, bag #5 in Beaker with water and bag #7 in the Beaker with 40% sucrose solution. At the beginning of the experiment all packets where weighed and recording in grams on the scale, all bags where then placed into their respective beakers. They were weighed at 15 minute intervals, for a total of 60 minutes. Upon weighing all the packets where rinsed and dried thoroughly to prevent any additional solution or water to cling to the exterior of the bags, the results were recorded in Figure 1.

The purpose of this lab is to determine the type of macromolecules that make up a particular unknown solution; using 3 different chemical tests. The first test consists of adding Benedict’s reagent to 12 different solutions; including the unknown. If any of the 12 solutions undergo a reaction in which they change colour (yellow, green, red or brown), then; the solutions contain simple sugars (ex. Monosaccharides).

The lab took place over the course of two days. The first day consisted of standard experimental tests in order to determine which macromolecules reacted with
