What is the relationship between Ka and Kb for a conjugate acid–base pair?
A.Ka × Kb = Kw
B.Ka + Kb = 14
C.Ka = Kb
D.Ka / Kb = Kw
Explanation
Core Concept
Multiplying the acid and base constants of a conjugate pair always yields Kw (1.0 × 10⁻¹⁴ at 25 °C). Stronger acids pair with weaker conjugate bases.
Correct Answer
AKa × Kb = Kw
