How to Calculate pKb
Formula
pKb = −log₁₀(Kb)
Where:
A lower pKb indicates a stronger base. pKa + pKb = 14 at 25°C for a conjugate pair.
हल किया गया उदाहरण
Ammonia has Kb = 1.8 × 10⁻⁵.
- 01pKb = -log₁₀(Kb)
- 02pKb = -log₁₀(1.8 × 10⁻⁵)
- 03pKb = 4.74
अक्सर पूछे जाने वाले प्रश्न
What does pKb tell you?
pKb measures base strength on a logarithmic scale. Lower pKb means stronger base. Each unit decrease represents a 10-fold increase in base strength.
How are pKa and pKb related?
For a conjugate acid-base pair at 25°C, pKa + pKb = 14. This comes from Ka × Kb = Kw = 10⁻¹⁴.
How do I convert pKb back to Kb?
Kb = 10^(-pKb). For example, pKb = 4.74 gives Kb = 10^(-4.74) = 1.82 × 10⁻⁵.
