Webb11 mars 2024 · The concentration of hydroxide ion of a solution whose pOH value is equal to 2.86 is 1.38×10⁻³ M.. How do we calculate the concentration of OH⁻? Concentration of hydroxide ion will be calculated by using the pOH value by using the below equation as:. pOH = -log[OH⁻] [OH⁻] = Given that value of pOH = 2.86. On putting values we get, [OH⁻] =
Webb16 juni 2016 · 2. In the moment from the video that you referred to, Sal was using the equation p K w = p H + p O H to find the p O H of the solution. p K w is equal to 14, since K w is equal to 1 × 10 − 14, giving us the new equation 14 = p H + p O H. We know that the p H of a 1M solution of H C l is zero from earlier on in the video. WebbHow to Convert pH and pOH at 25∘C 25 ∘ C. Step 1: Identify which value is given from the problem, pH or pOH?
