Aspirin absorption in carbohydrate solutions
The hypothesis that the presence of carbohydrate will not affect the rate of dissolution of aspirin has been proven to be partially true. The aspirin dissolved at almost the same rate in the cups with water and the dissolved sugar. However, it was slower to dissolve in the cup with corn flour. This could perhaps be due to the higher viscosity of the corn flour solution. Further investigation is necessary to ascertain if this is indeed the cause.
Aspirin is one of the most common pain killers available to the public, and can be found in most drugstores. It is both cheap and safe to use, provided of course, that it is properly administered in correct quantities. An interesting fact - it is estimated that Americans consume about 16,000 tons of aspirin tablets a year. Aspirin is used to reduce the risk of heart attacks and strokes. It is also used to relieve headaches, pain and fever.
This science fair project can also be repeated by using paracetamol or other similar medicines, instead of aspirin.
The experiment may also be modified to test the effects of temperature on the rate of dissolution of aspirin, by increasing the temperature of the solution from 25°C to 40°C.
