Aspirin Synthesis
Chemical synthesis of aspirin Aspirin, also known as acetylsalicylic acid, can be synthesized through a process called esterification. Here are the steps for the chemical synthesis of aspirin: Materials needed: Salicylic acid (2-hydroxybenzoic acid) Acetic anhydride Sulfuric acid Water Sodium bicarbonate Ice Instructions: In a flask, mix 10 g of salicylic acid with 20 mL … Continue reading Aspirin Synthesis

Quantitative Chemistry – calculating the percentage composition of iron in iron tablets.
Iron tablet titration is a common laboratory method used to determine the amount of iron present in a sample, such as an iron supplement tablet. This method involves reacting the iron in the tablet with a solution of potassium permanganate (KMnO4) to produce a purple colour. The endpoint of the titration is reached when the purple colour disappears, indicating that all of the iron in the tablet has reacted with the KMnO4.
Calculating the Molecular mass of a gas
The purpose of this experiment is to measure the volume and mass of a sample of butane, and to use these values to determine the molar mass.
