Webb4 feb. 2024 · The reason why pH = pKa at the half equivalence point is because that's where half the acid/base has reacted with the titrant. In other words, half of it is base/acid and the other half is salt. This goes beyond the content covered in this class but when you input the henderson hasselbalch equation, the pH = pKa. Hope this helps.

Webband the pH increases • When the moles of base added equals half the total moles of acid, the weak acid and its conjugate base are in equal amounts. The ratio of CB / WA = 1 and according to the HH equation, pH = pKa + log(1) or pH = pKa. • If more base is added, the conjugate base form becomes chivettes namesWebbShouldn't they be the same because pKa+pKb=14, and pH+pOH=14, thanks in advance.
