What is the ignition test of aspirin?

The ignition test of aspirin is a qualitative analysis method used to identify the presence of aspirin (acetylsalicylic acid) in a sample. In this test, the sample is heated, and if aspirin is present, it typically produces a characteristic odor of acetic acid due to the decomposition of the acetyl group. The test helps confirm the identity of aspirin in a mixture or pharmaceutical formulation. However, it is important to note that this method is not commonly used in modern analytical practices due to its potential hazards and the availability of more reliable techniques.
