{wiki=Dissociation_number}
The dissociation number, often represented as \\( pK_a \\) or \\( K_d \\), is a measure used in chemistry to quantify the degree to which a substance, usually an acid or a base, dissociates into its ions in solution. It reflects the strength of an acid or base in terms of its ability to donate or accept protons (H⁺ ions).
