Writing a chemical equation for aspirin titrated with NaOH

[Simone]

Hello,

I was wondering if anyone could help me in writing a chemical equation for aspirin + NaOH.
The aspirin equation is as follows:

C₇H₆O₃ + C₄H₆O₃ ------------------> C₈H₈O₄ + C₂H₄O₂
salicylic acid acetic anhydride acetylsalicylic acid acetic acid

Could someone please tell me exactly what is going on in the resulting reaction.

Thank-you and thanks for reading.

Aspirin C₈H₈O₄ reacts with NaOH as an acid with a base:

Code: Select all

C8H8O4 + NaOH = NaC8H7O4 + H2O
