Difference Between pH and pOH

Re: pH and pOH difference So pH is the measure of hydrogen ion concentration, [H+], while pOH is a measure of the hydroxide ion concentration, [OH-]. The scales for both are 1-14. However in most cases, the question will ask for pH. So remember that pH+pOH=14.

What is the difference of pH and pOH?

pH and pOH denote the negative log of the concentration of hydrogen or hydroxide ions. High pH means that a solution is basic while high pOH means that a solution is acidic.

What is relation between pH and pOH?

As with the hydrogen-ion concentration, the concentration of the hydroxide ion can be expressed logarithmically by the pOH. The pOH of a solution is the negative logarithm of the hydroxide-ion concentration. The pH of a solution can be related to the pOH. Consider a solution with a pH =4.0.

What is the pH of pOH?

In order to calculate the pH, take the negative log of the hydronium ion concentration. To find the pOH, simply subtract the pH from 14. In order to calculate the pOH, take the negative log of the hydroxide ion concentration. To find the pH, simply subtract pOH from 14.

Is pOH the opposite of pH?

pOH gives us another way to measure the acidity of a solution. It is just the opposite of pH. A high pOH means the solution is acidic while a low pOH means the solution is basic.

How is pH calculated?

To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = - log [H₃O⁺]. ... Example: What is the pOH of a solution that has a hydroxide ion concentration of 4.82 x 10^-5 M?

What does pOH mean?

pOH is a measure of hydroxide ion (OH^-) concentration. It is used to express the alkalinity of a solution. Aqueous solutions at 25 degrees Celcius with pOH less than 7 are alkaline, pOH greater than 7 are acidic and pOH equal to 7 are neutral.

What is the pOH if the pH is 4?

The pOH Concept

Consider a solution with a pH = 4.0. The [H⁺] of the solution would be 1.0 × 10^-4 M. Dividing Kw by this yields a [OH⁻] of 1.0 × 10^-10 M. Finally the pOH of the solution equals -log(1.0 × 10^-10) = 10.

What is the relation between pH and POS?

Complete answer:

pH is the measure of the acidity of solution while on the other hand pOH is measure of basicity of that solution, and when both have equal value, then that solution will be neutral. The pH of any solution can be related to pOH.

How do you know if pOH is acidic or basic?

Determine the pH of acidic and basic solutions. Determine the hydronium ion concentration and pOH from pH.
...
Knowing the dependence of pH on [H3O+], we can summarize as follows:

1. If pH < 7, then the solution is acidic.
2. If pH = 7, then the solution is neutral.
3. If pH > 7, then the solution is basic.

Why does pH and pOH equal 14?

pH and pOH are the log concentrations of protons and hydroxide ions, respectively. The sum of pH and pOH is always 14. This is because the product of proton concentration and hydroxide concentration must always equal the equilibrium constant for the ionization of water, which is equal to .

What is the pH of CsOH?

The pH of 7.52×10 ⁻⁴ M CsOH solution is 10.88 which is basic.

Can pH be negative?

If your acid solution is stronger than 1N, then you will get a pH less than 0 (a negative pH). It's possible. If the molarity of hydrogen ions is greater than 1, you'll have a negative value of pH. For example, you might expect a 12 M HCl solution to have a pH of -log(12) = -1.08.
