What is Ionization Constant?
The ionization constant (Ka for acids, Kb for bases) is the equilibrium constant for the ionization of a weak acid or base in water. For a weak acid HA, Ka = [H⁺][A⁻]/[HA], measuring the extent to which the acid donates protons to water. Larger values of Ka indicate stronger acids; pKa = −log(Ka) is a more convenient logarithmic scale used to compare acid strengths.
