This tool helps you easily calculate the dissociation constant (Ka) from the pH value.
How to Use the Ka from pH Calculator
To use this calculator, simply enter the pH value of your solution and the molarity (M) of the acid in the provided input fields. After filling the values, click the “Calculate” button. The calculator will then display the calculated Ka value.
Explanation of the Calculations
The calculation of the Ka (acid dissociation constant) from the pH value is based on the following steps:
- The pH value entered is first converted to the hydrogen ion concentration [H+] using the formula: [H+] = 10^(-pH).
- The Ka is calculated using the formula: Ka = ([H+]^2) / ([Acid Initial Molarity] – [H+]).
- The result is shown in a table format with the selected pH, Acid Molarity, and the calculated Ka value.
Limitations
This calculator assumes a monoprotic acid (one that donates only one proton per molecule) and ideal behavior (no significant interactions between ions in solution). Actual values might vary for polyprotic acids or in non-ideal solutions.
