Calculadora de pKa — Fórmula
## How to Calculate pKa
### Formula
**pKa = −log₁₀(Ka)**
Where:
- **pKa** = negative base-10 logarithm of Ka
- **Ka** = acid dissociation constant
A lower pKa indicates a stronger acid. pKa is more convenient than Ka for comparing acid strengths.

Ejemplo Resuelto
Acetic acid has Ka = 1.75 × 10⁻⁵.
- pKa = -log₁₀(Ka)
- pKa = -log₁₀(1.75 × 10⁻⁵)
- pKa = 4.76
