Can a ph be negative
WebSep 16, 2024 · Knowing the dependence of \(pH\) on \([H_3O^+]\), we can summarize as follows: If pH < 7, then the solution is acidic. If pH = 7, then the solution is neutral. If pH > 7, then the solution is basic. This is known as the \(pH\) scale. The pH scale is the range of value s from 0 to 14 that describes the acidity or basicity of a solution. You can ... 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.

Special electrodes are used to assess extremely low pH values. In addition to negative pH, it's also possible for pH to have a value of 0. The calculation also … where log is the base-10 logarithm and [H +] stands for the hydrogen ion … In other words, pH is the negative log of the molar hydrogen ion concentration or the …
WebSep 8, 2024 · Although pH values usually range from 0 to 14, it is definitely possible to calculate a negative pH value. A negative pH occurs when the molar concentration of hydrogen ions in a strong acid is greater than 1 N (normal). You can calculate a negative pH when an acid solution produces a molar concentration of hydrogen ions greater than 1. 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. Using the concentrations directly conveys a better sense than the pH scales. The …

The official definition of pH is: negative log of H+ activity, not negative log of H+ concentration, however. See pH Paradoxes: …
WebAt a pH of 7, this decreases to 0.0000001 M. At a pH of 14, there is only 0.00000000000001 M H+. pH stands for the “power of hydrogen” ³. The numerical value of pH is determined by the molar concentration of hydrogen ions (H+) ³. This is done by taking the negative logarithm of the H+ concentration (-log (H+)).
