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.
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.
pOH = 14 - pH 5 = 14 - pH 9 = pH

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.
First, since NaOH is a base you have to find the pOH first so you use the equation -> pOH = -log[NaOH] pOH = -log[NaOH] = -log[0.0111] pOH = 1.955 Then you use this equation -> 14 = pH + pOH to find the pH 14 = pH + pOH pH = 14 - pOH = 14 - 1.955 pH = 12.045 and that makes it basic Hope that helped. ^_^

We can subtract pOH from 14, using the formula pH + pOH = 14. This is only true at 14 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.
pH + pOH =14
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.
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
The pOH is 6,4.
