What is the Kb (Base Dissociation Constant) Calculator?

The Kb Calculator is a tool that helps users calculate the base dissociation constant of a weak base based on the hydroxide ion concentration [OH⁻] and the initial base concentration [B]. This is especially useful for chemistry students, educators, and laboratory professionals who want to quickly determine the strength of a base without performing manual calculations. By entering the relevant values, the calculator provides accurate results instantly, simplifying the analysis of weak base equilibria.

How to Use:

1. Enter Hydroxide Ion Concentration [OH⁻] (M): Input the concentration of hydroxide ions in moles per liter.
2. Enter Initial Base Concentration [B] (M): Input the initial concentration of the base before dissociation.
3. Click “Calculate”: The calculator computes the base dissociation constant (Kb) using the formula Kb=[OH−]2/[B]Kb = [OH⁻]^2 / [B]Kb=[OH−]2/[B].
4. Review Result: The output displays the Kb value in scientific notation for clarity and easy interpretation.
