This tool helps you convert the acid dissociation constant (Ka) value to the pH of a solution quickly and easily.
Explanation:
This calculator allows users to determine the pH of a solution from the molar concentration of the acid and its acid dissociation constant (Ka).
How to Use:
Enter the molar concentration (M) of the acid and its Ka value, then click “Calculate”. The calculator computes the hydrogen ion concentration [H+] and the pH of the solution.
How It Calculates:
The pH is calculated using the formula:
pH = -log10([H+])
Where [H+] (hydrogen ion concentration) is found by the equation:
[H+] = √(CHA * Ka)
Where:
- CHA: Molar concentration of the acid (M)
- Ka: Acid dissociation constant
Limitations:
This calculator assumes a simple monoprotic weak acid. For strong acids, polyprotic acids, or buffered solutions, the calculations become more complex and this simple model may not be accurate.
