What is the Ka (Acid Dissociation Constant) Calculator?

The Ka Calculator is a tool that helps users calculate the acid dissociation constant of a weak acid based on the hydrogen ion concentration [H⁺] and the initial acid concentration [HA]. This is useful for chemistry students, educators, and laboratory professionals who need to quickly determine the strength of an acid without performing manual calculations. By entering the relevant values, the calculator provides accurate results instantly, simplifying the analysis of weak acid equilibria.

How to Use:

1. Enter Hydrogen Ion Concentration [H⁺] (M): Input the concentration of hydrogen ions in moles per liter.
2. Enter Initial Acid Concentration [HA] (M): Input the initial concentration of the acid before dissociation.
3. Click “Calculate”: The calculator computes the acid dissociation constant (Ka) using the formula Ka=[H+]2/[HA]Ka = [H⁺]^2 / [HA]Ka=[H+]2/[HA].
4. Review Result: The output displays the Ka value in scientific notation for clarity and easy interpretation.
