Explanation of ir peaks of salicyic acid
WebAcetylsalicylic acid was administered orally in a single dose or in repeated doses at different times before legal interruption. The mean passage rates were about 6-15%. They were independent of the maternal serum … WebWhen aspirin is ingested, it is broken down to salicylic acid by the basic conditions in the small intestine. It is then absorbed into the bloodstream. Aspirin can be made by reacting salicylic acid with acetic acid in the presence of an acid catalyst. The phenol group on the salicylic acid forms an ester with the carboxyl group on the acetic acid.

WebIR Spectroscopy: IR spectroscopy is used to determine the most probable functional groups in a compound. This is possible because different functional groups have different peak shapes and different wavenumbers at which the peaks will show. As such, the IR spectrum of a compound can be treated as its fingerprint as it is unique for that compound.
