dissotsiatsioonikonstandiks

Dissotsiatsioonikonstandiks is the Estonian term for dissociation constant. It is a specific type of equilibrium constant that quantifies the extent to which a compound dissociates into its constituent ions in a solution. For a reversible dissociation reaction, such as the dissociation of an acid HA into H+ and A- ions, the dissociation constant (Ka) is expressed as the ratio of the concentrations of the dissociated products to the concentration of the undissociated reactant at equilibrium. A higher Ka value indicates a stronger acid or base, meaning it dissociates more readily. Conversely, a lower Ka value signifies a weaker acid or base. This constant is crucial in understanding acid-base chemistry, buffer solutions, and the behavior of electrolytes in aqueous environments. The dissociation constant is temperature-dependent. In the context of water dissociation, the autoionization constant Kw is a specific dissociation constant.
