Aspirin analysis Introduction Aspirin‚ which is also known as acetylsalicylic acid. C9H8O4 is the chemical format for Asprin. The chemical structure of aspirin: Aspirin is anti-inflammatory. Aspirin is prepared by chemical synthesis from salicylic acid‚ by acetylation with acetic anhydride. The fact that it is an acid allows us to quantify the amount of aspirin in a solution. We would do this by by using an acid-base titration. Sodium hydroxide (NaOH) will be used In this experiment as the

Titration Lab How Much Citric Acid is in Your Soda? PURPOSE To determine the molarity (concentration) of citric acid (H3C6H5O7) in various different citrus flavored sodas. BACKGROUND PRINCIPLES Popular sodas all strive for a somewhat sour (’tart’) flavor and manufacturers utilize acids to impart this taste. While there are a vast variety of different brands of sodas on the market‚ they can be broken into two main categories: dark or clear. This differentiation is not only a simple color

Before recrystallisation the crude aspirin could of included impurities such as: Acetic acid (a product of the reaction process). Recrystallisation helps to eliminate impurities; the precipitation process eradicates soluble impurities as aspirin has a higher precipitation temperature so converts to a solid while other impure components are
