Updated: 5/22/2024

Just like pH is the negative log of [H+], pOH is the negative log of the [OH-].

You can calculate pOH by taking the negative logarithm (base 10) of the hydroxide ion concentration in a solution. The formula for pOH is pOH = -log[OH-]. If you know the concentration of hydroxide ions (OH-) in a solution, you can plug that value into the formula to find the pOH.

Do you have the concentration of hydrogen? If so you can use the equation Kw = [H+][OH-], where Kw is the constant of water (1 X 10-14), [H+] is the concentration of hydrogen, and [OH] is the concentration of hydroxide. Once you have the concentration of hydroxide figured out, use the equation pOH = -log10[OH-].

You can find pOH if you know the pH of a substance by remembering the pKw = 14 = pOH + pH. Also remember that by definition, the p of something equals the -log(something), in this case -log(concentration of OH- ions).

The quantity pOH is the inverse of pH. The sum of the two always equals exactly 14 in any given liquid. So if the pH is 3, the pOH is 11, for example.

pH + pOH = 14

so for example: if our pH = 5

then our pOH = 14 - 5 = 9

as we know the atomic no of oxygen & hydrogen are 1 & 8 respectively . therefore when the combine they need a more bond hence form a OH molecule

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.

Calculate concentration of hydroxide ion with given pH?

To calculate the concentration of hydroxide ion from a given pH, you can use the formula: [OH-] = 10^(-14-pH) M. For example, if the pH is 9, then [OH-] = 10^(-14-9) = 10^-5 M.

What is pOH calculation?

pOH is the negative logarithm of the hydroxide ion concentration in a solution. It is related to pH through the equation: pOH + pH = 14 in an aqueous solution at 25 degrees Celsius. To calculate pOH, you can take the negative logarithm of the hydroxide ion concentration in moles per liter.

A solution of HCl has H 2.5 x 10-5 What is the pOH of this solution?

To find the pOH of a solution, first calculate the pH using the given [H⁺] concentration. In this case, [H⁺] = 2.5 x 10⁻⁵. Then use the equation pH + pOH = 14 to find the pOH. Thus, pOH = 14 - pH.

Calculate the OH- of a solution that has a pH of 2.40?

The pOH is the negative log of the OH- concentration. Thus, pOH = -log 2.0x10^-2pOH = 1.699 = 1.7

What is pH of the solution whose hydroxide in concentration is 4?

The pH of a solution is a measure of its acidity or basicity. To calculate the pH from the hydroxide concentration, you would first need to convert the concentration to a pOH value using the equation pOH = -log[OH-]. Then, you can calculate the pH using the relationship pH + pOH = 14.

What is the process for calculating the pH of a weak base solution?

To calculate the pH of a weak base solution, you first need to determine the concentration of the base and the equilibrium constant (Kb) for the base's reaction with water. Then, use the equation pH 14 - pOH, where pOH is calculated using the concentration of the base and Kb. Finally, calculate the pH using the pOH value.

What is the poH of 0.2 moles of sulphuric acid?

The pOH of a 0.2 M solution of sulfuric acid can be calculated by knowing the concentration and dissociation properties of sulfuric acid as a strong acid. Given the molarity of the solution, you can directly calculate the pH or pOH using the equation pH + pOH = 14 for a neutral solution.

To find the pOH of a solution when the H concentration is 1.7 x 10^-9 M, you can first calculate the pH using the formula: pH = -log[H+]. Then, you can find the pOH by subtracting the pH from 14, since pH + pOH = 14 in water. So, if the H concentration is 1.7 x 10^-9 M, the pH is 8.77, and the pOH is 14 - 8.77 = 5.23.

How do you calculate the pH or ion concentrations for acids and bases?

To calculate the pH of an acid or base, use the formula pH = -log[H+], where [H+] is the hydrogen ion concentration in moles per liter. To find the hydrogen ion concentration, use the equation [H+] = 10^(-pH). For bases, you can use the pOH = -log[OH-] formula to calculate the pOH, then find the hydroxide ion concentration with [OH-] = 10^(-pOH).

If the pH of a solution is 3, please determine it’s pOH?

The pH and pOH are related to each other through the equation: pH + pOH = 14 If the pH of a solution is 3, we can find the pOH by rearranging the above equation: pOH = 14 - pH = 14 - 3 = 11 Therefore, the pOH of the solution is 11.
