Ph to hydrogen concentration

WebJul 30, 2024 · The pH of a solution is a measure of the concentration of hydrogen ions in the solution. A solution with a high number of hydrogen ions is acidic and has a low pH value. A solution with a high number of hydroxide ions is basic and has a high pH value. The pH scale ranges from 0 to 14, with a pH of 7 being neutral. WebSep 30, 2024 · The numbers of the pH scale come from a formula for the hydrogen ion (H +) concentration. The equation for pH is: pH = -log[H +] The way a logarithmic scale works, chemicals that donate more hydrogen ions (protons) have lower pH values. These are acids. Chemicals that accept hydrogen ions have higher pH values and are bases.
