Acid dissociation constant - Wikipedia
In chemistry, an acid dissociation constant (also known as acidity constant, or acid-ionization constant; denoted ) is a quantitative measure of the strength of an acid in solution. It is the equilibrium constant for a chemical reaction
7.12: Relationship between Ka, Kb, pKa, and pKb
2021年4月28日 · For an aqueous solution of a weak acid, the dissociation constant is called the acid ionization constant (Ka). Similarly, the equilibrium constant for the reaction of a weak base with water is the base ionization constant (Kb). For any conjugate acid–base pair, \(K_aK_b = …
3.4: Acid base ionization constants (Ka and Kb relationship)
2021年1月10日 · For an aqueous solution of a weak acid, the dissociation constant is called the acid ionization constant (\(K_a\)). Similarly, the equilibrium constant for the reaction of a weak base with water is the base ionization constant (\(K_b\)). For any conjugate acid–base pair, \(K_aK_b = K_w\).

See below for a table of “Ionization Constants for Select Acids” and a table of “Ionization Constants for Select Bases”. Note that if the Ka value for an acid is listed, then the corresponding Kb value for its conjugate base will not be listed, and vice versa.
K a : The acid ionization constant - ChemTeam
Since the term K c [H 2 O] is a constant, let it be symbolized by K a, giving: This constant, K a, is called the acid ionization constant. It can be determined by experiment and each acid has its own unique value. For example, acetic acid's value is 1.77 x 10¯ 5.
Base Kb values were converted from Ka reference values using Kw = 1.01 x 10-14 at 25 °C. large. Lide, David R., Ed., Handbook of Chemistry and Physics, 84th ed., CRC Press: Boca Raton FL, 2003, 8-46 to 8-58. Values are all for 25 °C unless stated otherwise.
Acid and Base Ionization Constants - Lumen Learning
An acid ionization constant (Ka) is the equilibrium constant for the ionization of an acid. The acid ionization represents the fraction of the original acid that has been ionized in solution. Therefore, the numerical value of Ka is a reflection of the strength of the acid.
