Ph level of aspirin?

What pH is aspirin?

Aspirin (acetylsalicylic acid) is a weak acid. In water, its solution pH depends on concentration and temperature. A commonly cited pH for a typical aqueous aspirin solution is around pH 3 (acidic). [1]

Does aspirin have a single fixed pH?

No. Aspirin’s pH is not a single fixed value because pH changes with how much aspirin is dissolved and in what conditions. Stronger (more concentrated) solutions generally measure at a lower pH (more acidic), while more dilute solutions measure higher pH. [1]

How does aspirin’s acidity compare to other common acids?

Because aspirin is a weak acid, its solutions are typically more mildly acidic than strong mineral acids, but still clearly acidic (often in the low-pH range, such as around pH 3 for typical dilute solutions). [1]
