WebpOH or potential of hydroxide ion is a scale used to determine the hydroxide ion (OH –) concentration in a solution. It is a quantitative measure of the acidity or alkalinity of a solution. It equals the negative log of hydrogen ion (OH –) concentration. At pOH 7 solution is found to be neutral. WebSep 30, 2024 · The pH Scale of Common Chemicals. The pH scale shows how acidic or basic a chemical is in aqueous solution (mixed with water). The scale funs from 0 (most acidic) to 14 (most alkaline or basic), where 7 is neutral pH.Chemicals with pH values from 0 up to 7 are acids, those with a pH value of 7 are neutral, and those with pH values greater …

WebMay 15, 2024 · Pure water at ambient temperature has an equilibrium coefficient for [H +] and [OH -] of 1x10 -14. If the concentrations are equal, at 1x10 -7 each, the solution is neutral. The negative log of 1x10 -7 is 7. pH and pOH are both 7 at this point. This makes a convenient system for calculating the pOH once you know the pH: pH + pOH = 14.
