pOH from pH?

[jonathan chi 1J]

Can you find pOH if you have pH? and vice versa?

[Konmal Ali 1G]

Yes, you can find pOH if you have pH and vice versa. It can be done as long as you know that at room temperature, pOH+pH is equal to 14. As a result, if you have information on one, you can use that concentration to find the other. I hope this helps!

[AnoushkaBhat2J]

Can you find pOH if you have pH? and vice versa?

Yes, you can. This is because the equilibrium constant of water K_w = [H₃O⁺] [OH^-]. So when we take the log of both sides, you get log(1 x 10¹⁴) = log(H₃O⁺) + log(OH^-). So when you simplify both sides and multiply both sides by -1, you get
14 = -log(H₃O⁺) - log(OH^-), which is 14 = pH + pOH.

[Veronica Larson- 1I]

Yes, you can! If you know the pH, you can use the equation pH+pOH=14 (keep in mind that this is at standard temperature). So, for example, if you have a pH of 5, then the pOH would be 9.

[Aashna Sibal 2F]

Yup, you just use the equation the pOH + pH = 14. SO if you have the pH, you just subtract it from 14 to get the pOH.

[Abhinav Amanaganti 3K]

Yes, both pOH and pH will always add up to 14 so once you obtain one value, you can obtain the other with relative ease.

[Monse Mata 3D]

Yes, you can! I attached an image with the formulas and I hope it helps :)

[Aparna Pillai 1E]

Yes, you can find either pOH or pH given the other value, since both add up to 14. This is because the concentrations of H3O+ and OH- relate to one another (as one increases, the other decreases).

[Arad_Badiee_2B]

For instance, if a specific solution has a pOH of 12.90, then the pH would be found by doing the following. pH + 12.90 = 14. pH = 1.10.

[Jennifer Fuentes 2K]

The pH + pOH = 14

The pOH = -log[OH-]

The pH is measure of acidity of a solution whereas the pOH is a measure of basicity of a solution.

The two expressions are opposites expressions. As the pH increases the pOH decreases and vice versa. Both values equal 14.

To convert a concentration of into pH or pOH take the -log of molar concentration of the hydrogen ions or the molar concentration of the hydroxide ion concentration respectively.

[Anna Guan]

Yes, pOH + pH should equal 14. Think of them as opposite scales. In the pH scales any number below 7 is acidic, and above 7 is basic, while in the pOH scale any number below 7 is basic while above 7 is acidic.

[Elena Chan 2L]

Hi! As everyone said above, you can determine pOH from pH since they're related. As pH increases, pOH decreases and the same can be said the other way that when pOH increases, pH decreases. pH is the "potential of hydrogen" and pOH is the measurement of hydroxide ions in any concentration. They should add up to 14. Hope that helps.

[Nomi Heidari-Bateni 2K]

pOH = 14 - pH. In other words, pOH + pH = 14. If you know either pH or pOH, it is simple to find the other one. You can tell that there is a relationship between pH and pOH since they are dependent on the concentrations of H+ and OH- respectively, which are in themselves related to one another.

[Gianna Sciole 2F]

yes! pH = 14 - pOH and vice versa (pOH = 14 - pH). take for example, the pH of water is 7. both the H+ and OH- concentration are 10^-7. that means the pH would be 7 and the pOH would be 7. pH + pOH = 14, (7) + (7) = 14, which is what was stated above.

[Anne Hogue 2J]

Hi! All you have to know is that pH+pOH=14. So, if you are given the pOH just solve by subtracting the pH from 14 and vice versa.

[Shay Crookall 2L]

You absolutely can! You can do so from both the formulas to find pH/pOH as well as if you're just given the pH or the pOH (just needs to add up to 14!)

[Abigail Tran 14a]

Yes you can find pOH from pH. All you have to do is subtract pH from 14 because pH+pOH=14

[Lawrence Javelo Disc 3B]

Yes, you can find pOH from pH.
Equation: pH+pOH=14
If you are given a pH, you can plug it into this equation and solve for pOH, and this can go both ways.

[Madysen Ratsek 3L]

As everyone else said, the two simply add up to 14. Additionally, the rest of the calculations for pH and pOH can be determined from a single value. For example, if you are given the [H+] concentration of a solution, you can determine the pH with -log([H+]). Then you can subtract the result from 14 to get pOH. Similarly, you can get reverse the equation if you are given the pOH of a solution, you can determine the [-OH] by doing 10^-pOH (also 10^-pH from [H+]). It is all a matter of small calculations, which I think are easy wins for the final! Best of luck :)

[Albert Chen 1G]

pOH + pH = 14. So, you are able to find one if you have one
For example, if pH= 3.
Then pOH = 11.

[Samir Panwar]

Yes, the pH and pOH must add up to 14, so if you have one of them just subtract from 14 to find the other value.

[Jamie Lau 2J]

If you have the pH, you just have to subtract the value from 14 to get the pOH. If you have the pOH, you do the same thing for the pH. The equation is pH+pOH=14

[Claire Kim 1F]

Can you find pOH if you have pH? and vice versa?

Yes you can. 14-pOH=pH and 14-pH=pOH. If you have one value from pH, pOH, [H+], or [OH-] then you are able to find the values for the rest in the list.

[Joellen 1B]

yes. pH+pOH is equal to 14, so you would just have to subtract whichever one you have from 14.

[Lawrence Javelo Disc 3B]

14 = pOH + pH. You can use this equation to solve one if you have the other.

[Violet Mbela 2B]

Yes, you can! I attached an image with the formulas and I hope it helps :)

Thank you so much! This image is super helpful!

[Kassidy Patron 1L]

Yes, you can! You simply use the equation pOH + pH = 14. Knowing this, you can also find OH from H and vice versa because we know p = -log!

[Ayla3H]

At room temperature, the sum of pH and pOH always equals 14. Therefore, if we know one and we know that the solution is under room temperature conditions we can find the other.

[kareena_prasad]

Yep! All you need to do is 14 - pH to get pOH and 14 - pOH to get pH.

[Valerie M Dis 2E]

You can calculate pOH from pH with : 14-pH=pOH. You can also calculate it vice versa.

[Daniel N]

14-pH = pOH and 14-pOH=pH

[Baffour Adusei 1L]

Yes you can, pOH = 14 - pH.

[sophiavmr]

Yes, pOH=14-pH

[Kelly McFarlane]

pH + pOH = 14 so if you are given one value or the other you can find the other.

[isabella garcia - 1G]

When you have one of the values, you can always find the other because pH + pOH = 14 (at room temperature). So the pOH would be 14-pH

[Shannon Clark 1F]

Yes you can find pOH from pH and vice versa! :)

Since pH and pOH add up to 14, subtracting the pH from 14 will give you the pOH, and subtracting the pOH from 14 will give you the pH!

[Kaitlyn_Urquilla_1I]

Yes! As long as you have pOH or pH, you can always find the other. Since pH + pOH = 14, you can just use this equation and the one you know (pH or pOH) to get the one you do not know.

[Neeti Indiresan 3I]

pOH+pH = 14, so given either, you can find the other. This also allows you to calculate [H3O+] and [OH-].

[raynebunado]

Yes you can! To do so take 14.00 – pH = pOH

[Shania Garrison Discussion 3E]

Yes! The equation is 14= pH + pOH

[Jelix Tsan 2H]

pOH is calculated by subtracting your calculated pH value from 14, while pH is calculated by subtracted your calculated pOH value from 14. This is how you would be able to determine both values if you already know one.

[Mahika Saoji 3K]

Hi! First, to find the pH value, you use this equation: pH=-log[H+]. Once you have the pH value, you can subtract it from 14 to find the pOH. The highest pH attainable is 14, therefore the following equation exists: pH + pOH = 14. If you are trying to find the pH when given [OH-] you have to first find the pOH. The equation for pOH is pOH=-log[OH-]. You just subtract the pOH value from 14 to find your pH! I hope that helped!

[Aashna Sibal 2F]

Yup! As the other answers have said, pOH+pH = 14. Therefore, if you have just the pH, you subtract it from 14 to get the pOH. And if you have the pOH, you subtract it from 14 to get the pH.

[Omar Alkhalili 1J]

Hello! Yes, you can! pH and pOH add up to 14, so if you know one you can just subtract it from 14 to find the other.

[Diya Kar]

One can derive the pOH from pH because the addition of 2 equals 14. The concentrations of [H+][OH-] = 1.0 * 10^-14 and when anti logged is 14.

[Nathalia Garibay 1D]

Hi Jonathan.

pOH + pH = 14, thus you can solve for pOH by pOH=14-pH. This is also possible for finding pH from pOH

[Xzandalyn Kallstrom 2C]

At room temp., pOH+pH= 14, so you can subtract either the pH or pOH from 14 to get the other value. You can also use pOH or pH values to get OH- and H+ concentrations using this chart below, hope this helps :).

[005502505]

Yes! pOH is equal to the negative log of the PH value, and vice versa.

[Ainsley DeMuth 1H]

Yes, this is a calculation that can be done. If you are given the pH or the pOH, you just have to subtract the given number from 14 to find its counterpart. The formula is pH + pOH = 14.

[Kiana Rogers 1E]

yes, pOH + pH = 14.

[benkw_3I]

At room temp., pOH+pH= 14, so you can subtract either the pH or pOH from 14 to get the other value. You can also use pOH or pH values to get OH- and H+ concentrations using this chart below, hope this helps :).

Wow thank you for the chart! This is great summary for changing between pOH and pH as well as the pure concentrations of OH and H

[amreen_sandhu1k]

Yes! At room temperature (25 degrees Celsius) you can assume that the pH + pOH = 14. Using this equation you can plug in the value for pH/pOH in order to solve for the missing value.

[Andrew Greenberg 2D]

Yes. The pH and the pOH will add up to 14. You can use 14-pOH=pH or 14-pH=pOH.

[Audric Banuelos 1A]

Yes you can find pH from pOH and vice versa. Because pH + pOH = 14, all you need is either pH or pOH and then subtract it from 14. For example, if the pH is 5, the pOH would be 9 because 14 - pH = pOH / 14-5=9. The same method would be used to finding pH if pOH is given.

[Joyce Lee 1K]

pOH can be found from pH since pOH + pH = 14. Thus, when looking for the pOH we can use the equation 14 - pH.

[Reese R 1E]

pOH + pH = 14

pH = 14 - pOH

pOH = 14 - pH

pH = -log[H3O+]

pOH = -log[OH-]

[janice]

you can find the pOH from the pH by subtracting the pH from 14.

[HenrikZhang2K]

Yes. pH and pOH add up together to 14. So if you know one, it is easy to get the other.

[George]

you can just use the formula pOH +pH = 14

[Cameron Tran 3E]

Can you find pOH if you have pH? and vice versa?

Yup!! You can also find [OH-] and [H+] if you have a pH or pOH.

[Emily Lee 2H]

Yes, because pH+pOH=14 and if you have either you can just subtract that value from 14 and get your answer!

[Dakshesh Rana 3L]

ph+poh=14
you can just always put the values you have in this equation and solve for the desired values.

[Anabelle Pham 2C]

Yes, you can find it. pOH+pH=14. So, if you find pOH you can subtract by 14 to find pH and vice versa.

[Isabelle Kim 3E]

Yes, you simply use the equation that shows us the relationship between pH and pOH, which is the sum of both is 14.0

[Shania Hao 3L]

Yes, pOH and pH are related by the equation pH + pOH = 14. Therefore, if you have one value, you can easily find the other since they are related by this formula.

[renee chowdhry 1A]

Can you find pOH if you have pH? and vice versa?

Yes, you can. Since the formula is pOH + pH = 14 (for 25 degrees celsius), if you have either pOH or pH you can subtract it from 14. For example, if the pH is 6, you can subtract 14 from 6 (14 - 6 = pOH). The pOH would be 8.

[charliea100]

If given pH or pOH: pOH+pH= 14
If given concentrations: [OH-][H3O+]=1.0x10^-14
Then, the pOH would be -log[OH-] and pH would be [H3O+].

Hope this helps!
