Can a ph be negative

WebWhen you are given the molarity of an acid solution, and asked to determine the pH, a molarity greater than 1 produces a negative pH. Is this possible? Barry Bosco It's possible. If the molarity of hydrogen ions is greater than 1, you'll have a negative value of pH. For example, you might expect a 12 M HCl solution to have a pH of -log(12) = -1.08. WebJan 30, 2024 · A pH = -0.30 is equivalent to a \(\ce{[H+]}\) of 2.0 M. Negative pH values are only for academic exercises.
