Henderson Hasselbalch Equation

2. Water / Henderson Hasselbalch Equation / Problem 4

Problem 4

Calculate the pH of a solution with a pKa of 5.0 and a conjugate base to conjugate acid ratio of 0.5 using the Henderson Hasselbalch equation.

A

pH = 5.0 + log(0.5) = 4.5

B

pH = 5.0 + log(0.5) = 5.5

C

pH = 5.0 + log(0.5) = 4.7

D

pH = 5.0 + log(0.5) = 5.3
