Acid Dissociation

Match the following terms with their correct definitions:

• acid-ionization constant

• can act as both a Brønsted-Lowry acid and a Brønsted-Lowry base

• amphoteric substance

• the equilibrium constant for the dissociation of an acid

• strong acid

• poor proton acceptors

• weak acid

• do not dissociate completely into ions because only a portion of their molecules loses protons

• weak base

• give up protons easily and ionize completely
