Which Henderson equation is not correct?
Correct answer: C. pH = pKa - log [salt]/[acid].
- A. pH = pKa + log [salt]/[acid].
- B. pH = pKa-log [acid]/[salt].
- C. pH = pKa - log [salt]/[acid].
- D. Pka =pH-log[salt]/[acid].
Explanation
The only incorrect form is:pH=pKa−log[salt]/[acid]

About Buffer Solutions
Buffer solutions resist changes in pH when small amounts of acid or base are added, using a weak acid and its conjugate base or a weak base and its conjugate acid. Work includes buffer action, the common-ion effect, Henderson-Hasselbalch calculations, buffer capacity, and the difference between acidic and basic buffers.
