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

∙ 14y agoif 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.

Is POH organic?
pOH is a measure of concentration of OH- ions. pH + pOH = 14 mostly this is used in inorganic chemistry
What is the pOH range of bases?
An acidic solution will have a pOH ranging from 7 to 14
What is the pOH equation How can pOH be determined from pH?
pH + pOH =14
What is the pOH of a solution that has a POH OF 3?
3
How do you calculate OH- with a ph of 1.12?
pH + pOH = 14. So pOH = 14 - 1.12 = 12.88 pOH = -log[OH-] [OH-] = 1.31 x 10-13 M
Is POH organic?
pOH is a measure of concentration of OH- ions. pH + pOH = 14 mostly this is used in inorganic chemistry
How does the POH scale form PH scale?
pH + pOH = 14 pH is a measure of the hydrogen ion concentration, [H+] pOH is a measure of the hydroxide ion concentration, [OH-] pH = -log10[H+] pOH = -log10[OH-]
If pH equals 4 what is the poh?
The pOH is 6,4.
What is the solution's pH and pOH?
pH and pOH are a measure of the concentration of the hydronium ions and hydroxyl ions respectively in the solution. pH = -log[H+] pOH = -log[OH-] and they are related: pH + pOH = 14
What is the pOH range of bases?
An acidic solution will have a pOH ranging from 7 to 14
PH is a measure of?
pH and pOH are both logarithmic scales measuring the acidity (or basicness) of a solution. pH is based on the amount of H+ (hydrogen ions), and pOH is based on the amount of OH- (hydroxide ions) in the solution. You can calculate pH if you know the H+ activity: pH = - log10 (H+) pOH is calculated the same way, except with OH- instead of the H+ ions. pOH is also equal to 14 - pH. This is because the pH and pOH scales go from 0 to 14. A solution that is very acidic will have a low pH number and a high pOH number. Conversely, a very basic solution will have a low pOH and a high pH. Water is a neutral solution and has a pH and pOH of 7, which is in the middle.
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?
pH + pOH =14
If the pH of a solution is 10.7, what would the pOH be?
The pOH is 6,4.
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.
What is the the pOH if the pH of a solution is 7.6?
pOH +pH=14 pOH+7.6=14 pOH=(14-7.6)=6.4
What is the pOH of an acid that has pH of 2?
It will have a pOH of 12. Because pH+pOH=14
