https://doi.org/10.1351/goldbook.ST06785

Definition:
An equilibrium constant that expresses the propensity of a substance to form from its component parts. The larger the stability constant, the more stable is the species. The stability constant (formation constant) is the reciprocal of the instability constant (dissociation constant).
