Which of the following relationships is correct for a conjugate acid-base pair?
Correct answer: B. Ka x Kb = Kw
- A. Ka=1/Kb
- B. Ka x Kb = Kw
- C. pKw=-logKw
- D. None of these
Explanation
For any conjugate acid-base pair in aqueous solution, the product of their dissociation constants equals the ionproduct constant of water:

About Acids, Bases and Salts
Acid and base behaviour is explained through the Bronsted-Lowry transfer of protons and the Lewis donation or acceptance of electron pairs. The topic includes pH, pOH, ionisation and water equilibrium, plus salt formation and hydrolysis, where a salt solution may become acidic, basic or neutral.
