Aspirin is synthesized from salicylic acid and acetic anhydride. This includes detailed guides for the pre-lab, information sheet, post-lab, and quiz questions. Synthesis of aspirin lab account.

Synthesis of aspirin lab calculations

Synthesis of aspirin lab calculations picture This image illustrates Synthesis of aspirin lab calculations.

How is the percent yield of aspirin calculated?

Percent yield is calculated by (Mass of dried, recrystallised aspirin) ÷ (Expected mass of aspirin). In this experiment, the percent yield is 76.7% yield which shows that it is almost fully pure and contains lesser impurities.

How is the synthesis of aspirin done in the lab?

Aspirin Synthesis Tap water was heated on a steam bath in a 250 mL beaker. The temperature of an alcohol thermometer was equilibrated in a beaker of room temperature tap water. Salicylic acid (1.00 g + 0.005 g) and acetic anhydride (2.0 mL + 0.05 mL) were added to each of four test tubes. Sodium acetate (0.20 g) was added to one test tube.

How is the melting temperature of aspirin determined?

The aspirin crystals are packed into the small capillary tubes and make sure they are all compressed without air gaps. Then they are placed into the melting apparatus. The melting temperature range of aspirin according to my experiment is between 134.2 ÌŠC to 136.1 ÌŠC.

How is acetic anhydride used to prepare aspirin?

For preparation of Aspirin, acetic anhydride is added to the measured amount of salicylic acid. Sulphuric acid is added and heated for a short period to complete reaction.
