The variable component of the Henderson-Hasselbalch equation relates the pH of a solution to:
Select one:
a. The equilibrium constant of the weak acid.
b. The inverse of the pOH.
c. The log ratio of [dissociated form]/[acid].
d. The weak acid's pKa (This option ws wrong)
Homework Answers
Option C is correct
variable component of the Henderson-Hasselbalch equation relates the pH of a solution is The log ratio of [dissociated form]/[acid]
If pH = pKa, then ratio of dissociated acid and associated acid is zero
With a change in pH and PKa, there will be a change in the ration of dissociated acid and associated acid
