Acid-Base Equilibria

reaction involving the transfer of a proton from an acid to water, yielding hydronium ions and the conjugate base of the acid

• base ionization / disassociation

• acid ionization / disassociation

• autoionization

• acid-base indicator

equilibrium constant for an acid ionization reaction

• acid ionization constant (K_a)

• ion-product constant for water (K_w)

• base ionization constant (K_b)

• triprotic acid

weak acid or base whose conjugate partner imparts a different solution color; used in visual assessments of solution pH

• conjugate acid

• monoprotic acid

• acid-base indicator

• pOH

a solution in which [H₃O⁺] > [OH⁻]

• basic

• diprotic acid

• acidic

• monoprotic acid

species that may either donate or accept a proton in a Bronsted-Lowry acid-base reaction

• amphoteric

• conjugate acid

• amphiprotic

• neutral

species that can act as either an acid or a base

• amphiprotic

• Brønsted-Lowry acid

• Brønsted-Lowry base
