INTRODUCTION:
, Aspirin is a generic term for acetylsalicylic acid. This substance was
first introduced in the late 1890s, that has become a ‘’non-steroidal anti-
inflammatory drug’’, non-opioid analgesic and antiplatelet drug which is
widely used for medicinal purposes. Aspirin will not react against the acetic
conditions of the stomach, yet it is hydrolysed in the intestines as it will
react on alkaline conditions to create ethanoate ions and salicylate.
Aim: In this practical, an Aspirin will be made by using laboratory
techniques and will identify the percentage yield and purity of the
substance.
