The "p" means "potential" and the "OH" means "hydroxide". OH- is the hydroxide ion. In chemistry, pOH is the inverse log of the concentration of hydroxide in a solution:

pOH = -log [OH-]

To better understand, think of the more common term pH. pH gives a measure of the concentration of hydrogen in a solution.

pH = -log [H+]

If the pH is less than 7, the solution is basic. If it is more than 7, the solution is acidic. The scale runs from 0 to 14.

If the pH is 7 exactly, the solution is neutral. Distilled water has a pH of 7. And what is water? H+ and OH-! Therefore, if the pH is 7, there are equal amounts of hydrogen and hydroxide, or pure water.

An easy way to calculate pOH is to find the pH and subtract that from 14 (the top of the pH scale). Basically, pH + pOH = 14. So an easy way to find pOH is:

pOH = 14-pH

pOH measures the concentration of hydroxide ions in a solution. It is the negative logarithm of the hydroxide ion concentration and is used to determine the basicity of a solution.

if you mean pH then it is the acidity of an object. water is at 7, neutral, battery acid is almost 0, low the number the more acidic, and some detergents are at 13-14 or a base.

An acidic solution will have a pOH ranging from 7 to 14


The sum of pH plus pOH?

The sum of pH and pOH is always equal to 14 in a neutral solution at 25Β°C. This is because pH is a measure of the concentration of H+ ions in a solution while pOH is a measure of the concentration of OH- ions. In a neutral solution, the concentration of H+ ions is equal to the concentration of OH- ions, resulting in a sum of 14.


Is POH organic?

POH stands for "Proof of History," which is a mechanism used in blockchain technology to verify and record the historical data of transactions or events. It is a digital concept and not related to organic products or materials.


What is the solution's pH and pOH?

To find the pH, calculate -log[H+] using the concentration of hydrogen ions [H+]. To find the pOH, calculate -log[OH-] using the concentration of hydroxide ions [OH-]. The pH and pOH are related by the equation pH + pOH = 14 for a neutral solution.


Can bases be measure on a pH scale?

Yes it is possible. For bases the pH values generally range over 7 to 14. Alternatively pOH can be used, where pH + pOH = 14.


What is the pOH equation How can pOH be determined from pH?

How does the pOH differ from pH?

pOH happens to be the negative log of hydroxide ion' s concentration while pH is the negative log of hydrogen ion's concentration. pH is used to measure the acidity or alkalinity of a solution.


PH is a measure of?

PH is a measure of the acidity or alkalinity of a solution, indicating the concentration of hydrogen ions present. PH values range from 0 to 14, with lower numbers representing acidity, higher numbers representing alkalinity, and 7 being neutral.
