WebbIn chemistry, pH (/ p iː ˈ eɪ tʃ /), also referred to as acidity, historically denotes "potential of hydrogen" (or "power of hydrogen"). It is a scale used to specify the acidity or basicity of … Webb6 mars 2024 · 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. As the concentration of H + ions in solution increases, acidity increases and pH gets lower, below 7 (see Figure 1). When pH is above 7, the solution is basic. Figure 1.
