At what pH does the equilibrium between acetaldehyde and its hydrate occur, given that the pKa of the hydrate is 12 and the equilibrium constant for the reaction is 0.5?
Q1. At what pH does the equilibrium between acetaldehyde and its hydrate occur, given that the pKa of the hydrate is 12 and the equilibrium constant for the reaction is 0.5?
Answer: 11
Explanation: Henderson-Hasselbalch equation relates pH, pKa, and ratio of conjugate base to acid.
