Regardless of … Webb6 mars 2024 · pH is an expression of hydrogen ion concentration in water. Specifically, pH is the negative logarithm of hydrogen ion (H +) concentration (mol/L) in an aqueous solution: pH = -log 10 (H +) The term is used to indicate basicity or acidity of a solution on a scale of 0 to 14, with pH 7 being neutral.
