The pKa of acetic acid is 4.75 , so aspirin is 104.75−3.5=17.78 times stronger than acetic acid. Nonetheless, an acid with a pKa below 0 (i.e. Ka>1 ) is generally considered a so-called “strong acid”. And its pH can easily be measured by experiment… What makes a weak acid aRead More →

Aspirin (2-ethanoyloxybenzoic acid or acetylsalicylic acid) hydrolyses to produce 2-hydroxybenzoic acid and ethanoic acid.
