The pH scale is an inverse of hydrogen ion concentration, so more hydrogen ions translates to higher acidity and a lower pH. Carbon dioxide and seawater
WebSep 19, 2024 · To define the pH scale as a measure of acidity of a solution. Because of its amphoteric nature (i.e., acts as both an acid or a base), water does not always remain as H 2 O molecules. In fact, two water molecules react to form hydronium and hydroxide ions: (16.4.1) 2 H 2 O ( l) ⇌ H 3 O + ( a q) + O H − ( a q) This is also called the self ...
