What Is pOH? Definition and Calculation - Science Notes and Projects
Jun 15, 2021 · In chemistry, pOH is a measure of hydroxide ion concentration. The pOH scale is the reverse of the pH scale. pOH and pH are ways of describing how acidic or basic an aqueous solution …
15.8: pH and pOH Calculations - Chemistry LibreTexts
Dec 12, 2025 · pH and pOH are defined as the negative log of hydrogen ion concentration and hydroxide concentration, respectively. pOH is related to pH and can be easily calculated from pH.
Calculating_pHandpOH - Purdue University
Calculating pOH To calculate the pOH of a solution you need to know the concentration of the hydroxide ion in moles per liter (molarity). The pOH is then calculated using the expression: pOH = - log [OH -] …
15.2 pH and pOH – Chemistry Fundamentals
The pH and pOH scales represent concentrations of [H A 3 O A +] and OH A, respectively. The pH and pOH values of some common substances at standard temperature (25 °C) are shown in this chart.

POH believes every adult and child must have a basic understanding of the disease process which continues to plague all of humanity. Take a moment to learn the POH way of preventing dental …
pOH and how to calculate it - ChemTeam
So, if I have a pOH = 4, I know that the pH = 10 and that this is a basic solution. In a similar way, if I know the pOH is 11, then the pH is 3 and this is an acidic solution. For the examples below, convert …
pOH Scale and Calculations - CK-12 Foundation
Dec 1, 2025 · The pOH scale is similar to the pH scale in that a pOH of 7 is indicative of a neutral solution. A basic solution has a pOH of less than 7, while an acidic solution has a pOH of greater …
pH, pOH, and the pH scale (article) | Khan Academy
While we could also describe the acidity or basicity of a solution in terms of pOH , it is a little more common to use pH . Luckily, we can easily convert between pH and pOH values.
16.4 Introduction to pH and pOH - Open Library Publishing Platform
pOH scale is fairly similar to pH, except instead of measuring the hydrogen ion concentration in moles per litre, it measures the hydroxide ion concentration in moles per litre.
pH and pOH | Chemistry for Majors - Lumen Learning
The pH and pOH scales represent concentrations of [H 3 O +] and OH −, respectively. The pH and pOH values of some common substances at standard temperature (25 °C) are shown in this chart.
