At 25 degrees Celsius, the sum of pH and pOH equals 14, as they represent the negative logarithms of the hydrogen ion concentration ([H+]) and the hydroxide ion concentration ([OH-]) in a solution, respectively. This relationship is based on the self-ionization of water.

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.
What value of pH will give a pOH value of 5?
A pH of 9 will give a pOH value of 5, as the sum of pH and pOH is always 14 in water at 25°C. This is because pH + pOH = 14 in water.
A solution has H plus equals 6.2 x 10-3 What is the pOH of this solution?
7.8
If you add more and more HCl to a solution what will happen to the pOH?
As you add more HCl to a solution, the pH of the solution will decrease (become more acidic), resulting in a decrease in pOH. This is because pH and pOH are inversely related in a solution.
How do you find pH and poh of a 0.002614M NaOH solution?
To find the pH of a 0.002614M NaOH solution, first find the pOH by taking the negative base-10 logarithm of the hydroxide ion concentration. pOH = -log(0.002614) = 2.583. Since pH + pOH = 14 for water at 25°C, pH = 14 - pOH = 14 - 2.583 = 11.417.

How can the pH of a solution be calculated if the pOH is known?
We can subtract pOH from 14, using the formula pH + pOH = 14. This is only true at 14 degrees Celsius.

What is the pH of neutral solution at 25 degrees Celsius?
The pH of a neutral solution at 25 degrees Celsius is 7. This means that the concentration of hydrogen ions (H+) equals the concentration of hydroxide ions (OH-) in the solution, resulting in a balanced pH level.
What is the pOH equation How can pOH be determined from pH?
pH + pOH =14
What is Considered the opposite of pH?
The opposite of pH is pOH. While pH measures the acidity of a solution, pOH measures the alkalinity or basic nature of a solution. The sum of pH and pOH in a solution at a given temperature is always equal to 14 at 25°C.
What if the pH of a solution is 7.6 what is the pOH?
The pOH is 6,4.
What is the pH if pKw is 14.26?
I will assume you are asking about the pH of pure water if pKw is 14.26. The relationship between pH, pOH, and pKw is as follows: pH + pOH = pKw. If it is pure, neutral water (no acids or bases present), then pH = pOH, so: pH + pOH = 14.26 2(pH) = 14.26 pH = pOH = 7.13
