Properties of Analgesics

Extracts from this document...

Introduction

Lab Report TITLE Properties of Analgesics SUMMARY The mass of three analgesics, aspirin, buffered aspirin, and acetaminophen is certainly different. The insoluble particles in each varied as well. If base is added to aspirin, it will neutralize. If it is added to buffered aspirin and acetaminophen, then the pH will increases. First, we found the masses of four tablets of each analgesic. Then, we ground them separately into a powder. Each was dissolved in water and filtered, leaving only the insoluble particles behind The mass of the uncrushed analgesics was compared to its insoluble parts. ...read more.

Middle

This was the insoluble materials of aspirin. The other two produced the same results, leaving behind insoluble particles. The buffered aspirin seemed to take longer to filter, followed closely by acetaminophen. The aspirin took the shortest amount of time. ANALYSIS AND INTERPRETATION The masses of the four tablets for each analgesic was: aspirin tablets were 1.929g; buffered aspirin was 2.810g; and acetaminophen was 2.194g. After filtering, the mass of the insoluble material for aspirin was 0.637g; buffered aspirin was 0.676g; and acetaminophen was 0.733g. The pH change varied from each analgesic. ...read more.

Conclusion

Aspirin is the most acidic of the three, so it should be avoided by those that have stomach coagulation or ulcers, as the acid could make its way into the lining aggravating the stomach. In this case, buffered aspirin could be used, since it contains the least amount of insoluble material. Acetaminophen could be used if one has an allergy to aspirin. EXTENSIONS A grain is a metric equivalent to 0.0649 grams. It is 1/7000 of a pound. So for a 300mg dosage of aspirin, one would be taking 4.61 grains of aspirin. For a 325mg dosage (standard Tylenol) of acetaminophen, one would take 5 grains. For 350mg of buffered aspirin, one would take 5.39 grains. ?? ?? ?? ?? Zachary May 8/23/01 5th ...read more.

  1. Explain Aristotle idea of the four causes.

    Thus, Aristotle concludes that the natural scientist should study enmattered forms. (Physics, 194a25). This analogy to crafts, however, only establishes that the natural scientist should consider both formal and material causes. Aristotle will go on to give arguments for the remaining causes in this chapter, but they are complex and, frankly, poorly understood.

  2. Investigation into the physical properties of glass.

    To prevent the glass from breaking you need to make it harder for the surfaces or edges to be under tension. To do this you must compress the glass along its surface. Heating the glass forces it to expand. When the glass is removed out of the 1200 F tempering oven, air is applied to the surface of the glass.
