Small samples of acetaminophen‚ acetylsalicylic acid‚ cellulose‚ starch‚ and caffeine were obtained. These samples were then placed into seperate sets of test tubes that contained water‚ acetone‚ or dichloroethane. Solubilities were then tested for each sample in each solution which can be seen in Table 5. Next‚ four random pills were obtained and weights were taken of each. Each of the pills were grinded up using a separate mortar and pestle. The grinded up pills were then weighed. The grinded

Polymers can be made out of starch which is composed of long chains of glucose molecules. This study focuses mainly on making biodegradable plastics‚ which is certainly safer than non-biodegradable plastics‚ from potato starch. Biodegradable plastics made from raw materials are completely reusable and can be composted easily. Potato starch contains minimal protein and fat. Potato starch is a Polymer made of long chains of glucose units joined together. Potato starch contains two polymers: Amylopectin
