23. Acetylsalicylic acid, commonly known as ASA, is the most widely used drug in the world. ASA has the chemical formula, C8H7O2COOH, and a Ka of 3.27 X 10 – 4 mol/L. What is the pH of a 10 mol/L ASA solution?

The pH of the ASA solution is 1.24

If the solution is 10 M (as in 10.0---I can't tell if it is 0.10 or 10), then 1.24 is the correct answer for the pH.

    Okay, so apparently ASA and FeCl3 form a violet complex and FeCl3 forms with phenol groups to make purple. Looking at the structures of ASA and salicylic acid, only salicylic acid has the phenol group. The thing is, salicylic acid
