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!

I recently had a new mri of the brain woith and w/o contrast there was two small white spots mr nuerolgist told my wife and myself that i probably have ms,he just needed to wait for the blood work to come back.I am very sure he had the blood work already because i called the lab and they said that the report had been faxed twice the day before.I really dont feel very comfortable with this guy.I called my primary care doc and left her a message what his diagnoses was, she called me back and said she had spoken with him and he told her that he was not sure if i have ms. My primary also said that it is very common to have white spots on the brain,and dont jump to any conclussions. Very confused and emotionally spent person here,i really dont have much left as of emosions anymore with everything that i,ve been thru.Falcons117
