WebpOH or potential of hydroxide is a criterion for measuring the hydroxide ion concentration in the solution. It is used to determine the acidity or alkalinity of a solution. pOH is equivalent to the negative log of hydroxide ion (OH –) concentration. pH = – log [OH –] At pOH 7, the solution is neutral. Web1. Enter a value. Exponential numbers should be entered using E to represent 10^. For example 1.0x10-7 should be entered as 1.0E-7 (no spaces!). 2. Select pH, pOH, [H+] or [OH-]. 3.
