Extended Experimental Investigation Cold Pack Year 12 Chemistry Abstract: Cold packs are based on the principle of endothermic reactions‚ which means a reaction that absorbs heat from the surrounding resulting in a temperature drop. Due to this temperature drop‚ cold packs have many benefits when it comes to injuries such as sprains and strains. It cools the local tissue and reduces bleeding‚ swelling and pain. It also aids in a speedy recovery. The most commonly used

This results in acetylsalicylic acid or "aspirin". Acetylsalicylic acid is synthesized in labs and does not occur naturally. It is produced from adding acetic anhydride to salicylic acid in the presence of sulfuric acid (H2SO4)‚ an acid catalyst: (Diagram from 1) The impurities left over (unreacted salicylic acid‚ acetic acid and sulfuric acid)
