What is the pKa Calculator?

The pKa Calculator is a tool that helps users determine the pKa value of an acid, which is the negative logarithm of its acid dissociation constant (Ka). This is useful for chemistry students, educators, and laboratory professionals who want to quickly find the pKa of an acid without performing manual logarithmic calculations. By entering the Ka value, the calculator provides the pKa instantly, allowing easy comparison of acid strengths and a better understanding of chemical equilibria.

How to Use:

1. Enter Acid Dissociation Constant (Ka): Input the Ka value of the acid.
2. Click “Calculate”: The calculator computes the pKa using the formula pKa=−log⁡10(Ka)\text{pKa} = -\log_{10}(Ka)pKa=−log10​(Ka).
3. Review Result: The output displays the pKa value with four decimal places for clarity and easy interpretation.
