The pH from pKa calculator tool quickly determines the pH of a solution using its pKa value and the concentrations of the acid and conjugate base.
How to Use the pH from pKa Calculator
To use the calculator, simply enter the pKa value of the acid and the concentrations of the acid and its conjugate base in the respective fields. The pH of the solution will be displayed in the results section after you press the calculate button.
Calculation Explanation
The pH is calculated using the Henderson-Hasselbalch equation:
pH = pKa + log10([Base]/[Acid])
This equation relates the pH, the pKa of the acid, and the ratio of the concentrations of the conjugate base and the acid.
Limitations
This calculator assumes ideal conditions and may not accurately represent real-world scenarios where multiple variables could affect the pH. For precise measurements, especially in complex solutions, experimental determination of pH is recommended.
