WebJan 30, 2024 · The pH scale is logarithmic, meaning that an increase or decrease of an integer value changes the concentration by a tenfold. For example, a pH of 3 is ten times more acidic than a pH of 4. Likewise, a pH of 3 is one hundred times more acidic than a pH of 5. Similarly a pH of 11 is ten times more basic than a pH of 10. Properties of the pH Scale WebApr 26, 2024 · A solution can only become more acidic if there is a higher level of hydrogen ions than hydroxide ions. In the case of pure water, the concentration of hydrogen ions and hydroxide ions never changes, so water is always neutral regardless of whether its pH level changes.
