WebApr 8, 2024 · 1 Answer. You are most likely getting an inaccurate value. As anticipated in Poutnik's comment above is difficult to reliably measure a p H of very acidic solution but the p H scale is indeed open, and negative p H are a real thing. It is easy and more meaningful to state a very high concentration or activity rather than reporting inaccurate p H. The answer is yes! The pH scale usually runs from 0 to 14, but if the molarity of hydrogen ions in a strong acid is greater than one you’ll calculate a negative pH value. For example, the calculated pH of 12M HCl (hydrochloric acid) is: pH = -log [H +] pH = -log [12] pH = -1.08.
