Acid Dissociation Constant (Ka) Calculator







Formula

To calculate the Acid Dissociation Constant (Ka):

\[ Ka = \frac{A \times H}{HA} \]

Where:

What is the Acid Dissociation Constant?

The Acid Dissociation Constant, \( Ka \), is a quantitative measure of the strength of an acid in solution. It is the equilibrium constant for the dissociation of an acid into its conjugate base and a hydrogen ion. The higher the value of \( Ka \), the stronger the acid.

Example Calculation

Let's assume the following values:

Step 1: Multiply the concentration of the conjugate base by the concentration of hydrogen ions:

\[ A \times H = 0.1 \times 0.01 = 0.001 \]

Step 2: Divide the result by the concentration of the chemical species:

\[ Ka = \frac{0.001}{0.1} = 0.01 \]

The Acid Dissociation Constant \( Ka \) is 0.01.
