Aspirin absorption in carbohydrate solutionsFeatured science projectScience project video


This science fair project was performed to ascertain if carbohydrate solutions will make aspirin dissolve faster and improve their absorption. The testing was done by placing aspirin in a cup of water, a cup of water with sugar added and a cup of water with corn flour added.


The presence of carbohydrates will not affect the rate of dissolution of aspirin.

Scientific Terms

Aspirin, analgesic, anti inflammatory, acetylsalicylic acid, thromboxane



Aspirin is an analgesic medication used to relieve minor pains and reduce fever, and is also an anti-inflammatory medication. It is one of the most common and cheapest pain killers that can be bought easily over the counter in most drugstores.
The aspirin tablets are produced by mixing corn starch, distilled water and acetylsalicylic acid, which is also the active ingredient in the tablet. Other ingredients like the binding agents and fillers are also added and mixed together. The mixture is then compressed into tablets. Aspirin tablets are available in various sizes, weights, hardness and shapes depending on the dosages.

Aspirin is also used to help prevent blood clots, strokes and heart attacks. This is because of the ability of aspirin to inhibit thromboxane production. Aspirin is also given to patients immediately after a heart attack, in order to avoid a second attack and also to prevent cardiac tissue from dying. Some of the known side effects of aspirin are stomach ulcers, tinnitus, stomach bleeding and Reye’s syndrome.
