Chemical Properties

Aspirin is typically a very stable molecule, it tends to mainly react with moisture. As aspirin is exposed to moisture it undergoes a process called hydrolysis. This occurs when a chemical bond is separated due to introducing water into the factor. In the case of aspirin undergoing hydrolysis, it causes the aspirin molecules to split into acetic and salicylic acid. Another way of understanding this process is that due to the addition of water aspirin in a sense goes through the reverse process. The exposure to moisture tends to cause old and expired aspirin pillls to smell like vinegar, this is also due to hydrolysis.
Common Names:
Aspirin, Acetylsalicylic acid, 2-Acetoxybenzoic acid, Acetylsalicylate

Organic or Inorganic?
Since aspirin is synthetically derived from salicylic acid that has been extracted from willow bark, it is therefore considered to be a synthetic organic molecule.
