WebMar 16, 2024 · The pOH is a similar measurement to the pH and correlates to the concentration of hydroxide ions in a solution. The formula for the pOH is: pOH = -log10 ( [OH-]) In specific conditions (aqueous solutions at room temperature), we can define a useful relationship between pH and pOH: pH = 14 - pOH What are some examples of pH? Webor if preferable, for bases, by analogy of acids and bases (we replace pH with pOH and pKa with pKb): [3.8] logD = logP + log 1 / 1 + 10 pOH-pKb. in the knowledge that pH + pOH = 14 and pKa + pKb = 14. When the pH and the pKa are only one unit apart, a simplified expression can be used: ...
What happens when pH is greater than pKb? : r/Mcat - Reddit
WebIt's been a while since I've done any of this, but I think you're making the mistake of saying 14-pKb = pKa. You may be thinking of 14-pOH = pH. Try using the Heylman equation instead.

Let's assume that both the acid's and conjugated base's concentrations are equal to 6 M. Utilize the equation: pH = pKa + log ( [A⁻]/ [HA]) pH = 6.4 + log (6 M/6 M) pH = 6.4 + log (1) pH = 6.4 + 0 pH = 6.4 The pH of our buffer is equal to 6.4.
