This tool helps you calculate the acid dissociation constant (Ka) for your chemical solutions quickly and accurately.

## Ka Calculator

This calculator allows you to calculate the acid dissociation constant (Ka) of a substance given its concentration and its ionized fraction. Enter the substance concentration in molarity (M) and the ionized fraction (α) which should be a number between 0 and 1.

### How to Use:

- Enter the substance concentration in molarity (M) in the first input field.
- Enter the ionized fraction (α) which is a number between 0 and 1 in the second input field.
- Click “Calculate” to get the result.
- The calculator will display the calculated Ka value in the “Result” field.

### Explanation:

The acid dissociation constant (Ka) is a quantitative measure of the strength of an acid in solution. It is calculated using the formula:

`Ka = (α * [HA]) / (1 - α)`

where **[HA]** is the concentration of the substance, and **α** is the ionized fraction.

### Limitations:

- The input concentration should be a positive number (>= 0).
- The ionized fraction should be a number between 0 and 1.
- The result might not be accurate if the inputs are very small or very large numbers due to potential floating-point precision issues.
