Basicity constant, Kb

Definition

The basicity constant, \(K_b\), measures the strength of a base in solution, specifically how well an amine can attract and hold a proton (H+). It quantitatively expresses the equilibrium between the amine in its basic form and its corresponding protonated form in solution.
