WebThe pH scale is used to rank solutions in terms of acidity or basicity (alkalinity). Since the scale is based on pH values, it is logarithmic, meaning that a change of 1 pH unit corresponds to a ten-fold change in H + ^+ + start superscript, plus, end superscript ion … Learn for free about math, art, computer programming, economics, physics, … Example: if you had a concentration of 10^-7 moles of H+ (pH 7) and suddely have … Learn for free about math, art, computer programming, economics, physics, … WebJun 15, 2024 · pOH = -log [OH – ] As with pH, pOH values range from 1 to 14, where 7 is neutral. The scales for pH and pOH are opposites of one another. A low pOH value indicates high basicity of alkalinity, while a high pOH value indicates high acidity. In contrast, a low pH indicates high acidity, while a high pH indicates high basicity. Why Use pOH? diabetic eye screening specsavers
