The poh of a solution is equal to
Webb12 juni 2024 · A fundamental equation to know regarding pH is that (near 25oC ), pH+pOH = 14.00. That is, near 25oC, the sum of the pH and pOH is always 14.00. Therefore, pOH = 14.00 − pH = 14.00 − 7.0 = 7.0. Since the pH and pOH are equal, this solution is said to be neutral; i.e. it is neither acidic nor alkaline (basic). Answer link. WebbAt 25 C, the autoprotolysis equilibrium for water requires the sum of pH and pOH to equal 14 for any aqueous solution. The relative concentrations of. Get detailed step-by-step explanations.

Did you know?
WebbIt is used to determine the acidity or alkalinity of a solution. pOH is equivalent to the negative log of hydroxide ion (OH –) concentration. pH = – log [OH –] At pOH 7, the solution is neutral. If the pOH value is less than 7, a solution will be alkaline, while a solution will be acidic if the pOH value is more than 7. We can use ... WebbCorrect option is A) We know, pH+pOH=14. Given, a solution has pOH equal to 13 at 298 K. Therefore, pH=14−13=1. Therefore, the solution is highly acidic. So, the correct option is …
