WebJun 9, 2024 · The higher the \(\ce{H^+}\) ion concentration is, the lower the pH of the solution. The pH scale is generally presented as running from 0 to 14, though it is possible to have a pH of less than 0 or greater than 14. For example, a highly concentrated \(3.0 \: \text{M}\) of \(\ce{HCl}\) has a negative pH. WebThe concentration of hydrogen ions can vary across many orders of magnitude—from 1 to 0.00000000000001 moles per liter—and we express acidity on a logarithmic scale called … chip ottley
