Equations for aspirin?

Question

What would the equations be with aspirin reacts with HCL and NaOH? I know the equations for Aspirin reacting with NaOH in distilled water. These are the equations I need to know:

Aspirin + 1mol HCL + 1 mol NaOH
Aspirin + 0.5mol HCL + 1mol NaOH
Aspirin + 0.25mol HCL + 1 mol NaOH

Aspirin + 1 mol HCL + 0.5mol NaOH
Aspirin + 0.5mol HC + 0.5mol NaOH
Aspirin + 0.25mol + 0.5mol NaOH

Aspirin + 1mol HCL + 0.25 mol NaOH
Aspirin + 0.5mol HCL +0.25mol NaOH
Aspirin + 0.25mol HCL + 0.25 mol NaOH

Just to check:
Aspirin + distilled water + 1 mol NaOH
Aspirin + distilled water + 0.5mol NaOH
Aspirin + distilled water + 0.25mol NaOH

Any help would be most appreciated!

Answer 1

I do not believe that aspirin, or acetylsalicylic acid, would react with acid, but indeed it will react with base. however, it is a relatively weak acid. Hence when you have a mixture of strong acid and strong base as well as aspirin, the strong acid and strong base would react FIRST. If there are extra base, aspirin would react with it. On the other hand, if there are extra acid, nothing would happen between the extra acid and aspirin.
