Web15 de jun. de 2024 · The pOH of an aqueous solution is the negative logarithm of the hydroxide ion (OH –) concentration. 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. pH is defined as the decimal logarithm of the reciprocal of the hydrogen ion activity, aH+, in a solution. For example, for a solution with a hydrogen ion activity of 5×10 (at that level, this is essentially the number of moles of hydrogen ions per litre of solution) the argument of the logarithm is 1/(5×10 ) = 2×10 ; thus such a solution has a pH … list of organic gases
