Fill in the blank.
weak bases react with to form the hydroxide ion and the conjugate of the base. concentration in solution does not affect whether an acid or a base is or weak.
the strength of an acid or a base is determined by the of the substance in solution.
the acid dissociation constant, is a quantitative measure of acid strength. a strong acid has a much ka than a weak acid. the ka of an acid is determined from measured values.
hydrochloric acid and sulfuric acid are ionized in solution and are acids. ethanoic acid, which is only about 1 percent ionized, is a acid. magnesium hydroxide and calcium hydroxide are strong
