Measures concentration of hydrogen ions

WebThe pH of a solution is a measure of hydrogen (H+) ion concentration, which is, in turn, a measure of acidity. Pure water dissociates slightly into equal concentrations of hydrogen and hydroxyl (OH −) ions: (5.16) An excess of hydrogen ions makes a solution acidic, whereas a dearth of H + ions, or excess of hydroxyl ions, makes it basic. WebJan 17, 2008 · The pH of a sample of water is a measure of the concentration of hydrogen ions. The term pH was derived from the manner in which the hydrogen ion concentration is calculated - it is the negative logarithm of the hydrogen ion (H +) concentration.
