For a laboratory experiment at my school I wanted to test how much salicylic acid there is in old Aspirin tablets. However, I am not quite sure how to do this. I know that a titration won't work, because it only tells how much acid there is in the Aspirin solution, but does not indicate how much of the salicylic acid is present.
Can someone help me to find a method to get quantitative data?
Thank you in advance for your answer!!
