Webb29 aug. 2014 · Solve for pOH. pOH = 14 - pH pOH = 14 - 1.5 = 12.5 When the pOH is solved, solve for the concentration by using log. pOH = -log[OH-] 12.5 = -log[OH-]-12.5 = log[OH-] … Webb6 mars 2024 · Theory 2: Due to complete dissociation, initial concentration of KOH is equal to OH - concentration. Equation 1: Relationship of pH + pOH = 14. Equation 2: pH = -log 10 [H 3 O +(aq)] Equation 3: pOH = -log 10 [OH -(aq)] Question #1. In the laboratory, there is a aqueous potassium hydroxide solution which was prepared by a student.
The poh of a solution is equal to - Math Tutor
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 ... WebbNotice, since we have two significant figures for the concentration, we need two decimal places for our pOH. So to find the pH, we know that pH plus pOH is equal to 14.00 at 25 degrees Celsius. So we can plug in the pOH of 2.70, and that gives us pH plus 2.70 is equal to 14.00. So the pH of the solution is equal to 11.30. orange county florida school board question
