Acid Ionization Equilibrium of Benzoic Acid

These flashcards cover the key concepts of the acid ionization equilibrium involving benzoic acid, including definitions of terms and equilibrium expressions.

Benzoic Acid (C6H5COOH)

A weak acid that ionizes in water to form benzoate ion and hydrogen ions.

Conjugate Base

The species that remains after the acid donates a proton; in this case, the benzoate ion (C6H5COO-).

Conjugate Acid

The species formed when a base accepts a proton; in the context of the equilibrium, it refers to the hydrogen ion (H+).

Acid Ionization Equilibrium Expression (Ka)

Ka = [C6H5COO-][H+]/[C6H5COOH], representing the ratio of the concentration of products to reactants at equilibrium.

Equilibrium Constant Ka

Value of 6.5 x 10^5 suggests that the products are favored at equilibrium.
