WebpH and pOH are two very similar things. If an acid has a pH of 6, then it will have a poH of 8. This happens since the pH scale is out of 14 and pH and pOH are basically opposites. So the formula for pH and pOH is pretty simple if you are given one … Web6 feb. 2024 · What is the formula of pOH? pOH is the measure of alkalinity, or hydroxide ion concentration, of a solution. If you know what the pH of the solution is, it gets easier to calculate its pOH value, as pH + pOH = 14. You could also apply the equation pOH = -log [OH-]. What is the pOH if the pH is 8? Hence, the value of pOH of the solution is 6 for ...

Web30 mrt. 2024 · The pOH can be easily determined by substituting the given value of [OH –] into the formula: pOH = -log 10 [OH –]. How to find the pOH of an aqueous solution from [H + ]? The pH of a solution can be determined by taking the negative logarithm of [H + ]. WebpOH is a measure of hydroxide ion (OH –) concentration. The pOH scale is similar to the pH scale in that a pOH of 7 is indicative of a neutral solution. pOH is used to express the alkalinity of a solution in where the pH is known.
