Buffer pH Calculator
Acidic Buffer:
pH = pKa + log₁₀([Salt] / [Acid])
Basic Buffer:
pOH = pKb + log₁₀([Salt] / [Base])
pH = 14 − pOH
⚗️ Introduction: Buffer pH Calculator 🔬
A Buffer pH Calculator is an advanced scientific tool designed to accurately compute the pH of buffer solutions using the Henderson–Hasselbalch equation. Buffers play a critical role in chemistry, biochemistry, pharmaceuticals, and environmental sciences by resisting changes in pH when small amounts of acid or base are added.
This calculator enables students, researchers, laboratory professionals, and educators to instantly determine buffer pH, acid–base ratios, and ionic equilibrium behavior without manual calculations. By integrating chemical thermodynamics, acid dissociation constants (Ka), and logarithmic pH relationships, this tool delivers precise, reproducible, and reliable results—essential for both academic and industrial applications 📊🧪.
