The Henderson-Hasselbalch equation is:
A.pH = pKa + log([base]/[acid])
B.pH = -log[H⁺]
C.Ka = [H⁺][A⁻]/[HA]
D.pOH = 14 - pH
Explanation
Core Concept
The Henderson-Hasselbalch equation pH = pKa + log([A⁻]/[HA]) is used to calculate the pH of a buffer solution, where [A⁻] is the conjugate base concentration and [HA] is the weak acid concentration.
Correct Answer
ApH = pKa + log([base]/[acid])
