Is aspirin soluble in water?

Aspirin is slightly soluble in water. It is also mildly soluble in acidic solutions, including gastric juices. It is more soluble in basic solutions, which make it easily dissolvable in the human intestines.

Aspirin is considered a weak acid, and when it is dissolved in water or when it becomes old, it often possesses a smell that resembles vinegar. This is because the process of hydrolysis produces acetic acid. In addition to treating pain and fever, aspirin is used as an anticoagulant treatment to prevent blood clots and heart attacks. It also shows promise in the prevention of certain cancers, such as those of the lower gastrointestinal tract.
