Aspirin's Sweetest Friend

Overview

Objectives/Goals My objective was to see if the presence of a carbohydrate (starch, complex sugar, fiber) affect the absorption rate of a Bayer Aspirin tablet. I hypothesized that there would be no significant change or differance with the presence of the carbohydrate. Methods/Materials My method of testing was done by submerging the plastic membrane filled with the aspirin, carbohydate and stomach solution into a beaker of distilled water. I checked the pH of the water in even increments of twenty seconds for two minutes and recorded the data. This infered that the aspirin was diffusing into the water because aspirin is acidic so that will allow the pH to drop. Results I found that the sugar had the quickest average of diffusion, in second came the aspirin with no carbohydrate, third came the starch which was followed by the fiber. Suprisingly the pH rose with the presence of the starch and fiber although it was a very small emount. I still haven't been able to determine why this occured. Conclusions/Discussion I conclude that my hypothesis was correct by there being no signifant change in the absoption rate of the Bayer Aspirin tablet with the carbohdrayte's presence. I belive this happened because the carbohydrate is not absobed in the stomach like the aspirin is.
