Aspirin Absorption in Carbohydrate Solutions

Medium
Aspirin Absorption in Carbohydrate Solutions | Science Fair Projects | STEM Projects
We'll explore how the presence of carbohydrates affects the rate of aspirin dissolution. We'll measure the pH of the solutions in three cups every minute for five minutes. One cup will contain only water, one cup will contain water and sugar, and one cup will contain water and corn flour.

Hypothesis

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

Method & Materials

You will fill three cups with bottled water. Add one teaspoon of sugar to the second cup and one teaspoon of corn flour to the third cup. Drop one tablet of aspirin in the first cup and measure the pH of the solutions in the three cups every minute for five minutes.
You will need three transparent cups, three aspirin tablets, pH paper, a stopwatch, a bottle of water, a teaspoon, a packet of sugar, and a packet of corn flour.

Results

The results showed that the aspirin dissolved faster in the cup with water and the cup with sugar added to the water. The pH reading decreased at almost the same rate. However, the aspirin was slower to dissolve in the cup with the corn flour.

Why do this project?

This science project is interesting because it explores how the presence of carbohydrates affects the rate of aspirin dissolution. It also shows how the pH of the solution changes over time.

Also Consider

Variations of this science project include using paracetamol or other similar medicines instead of aspirin, and testing the effects of temperature on the rate of dissolution of aspirin by increasing the temperature of the solution from 25°C to 40°C.
