If pKb for fluoride ion at 25°C is 10.3, the ionization constant of hydrofluoric acid in water at th — Ionic Equilibrium Chemistry Question
Question
If pKb for fluoride ion at 25°C is 10.3, the ionization constant of hydrofluoric acid in water at this temperature is (log 2 = 0.3)
Answer: A
💡 Solution & Explanation
pKa = 14 - pKb = 14 - 10.3 = 3.7. Ka = 10^-3.7 = 10^0.3 * 10^-4 = 2.0 * 10^-4.
