Problem 2
Match the key terms with the descriptions provided. (a) an acid that ionizes completely when dissolved in water (b) a model that describes acids as substances that generate \(\mathrm{H}^{+}\)ions in solution and bases as substances that generate \(\mathrm{OH}^{-}\)ions in solution (c) an aqueous hydrogen ion; \(\mathrm{H}_{3} \mathrm{O}^{+}(\mathrm{aq})\) (d) a solution in which the \(\mathrm{OH}^{-}\)concentration is greater than the \(\mathrm{H}_{3} \mathrm{O}^{*}\) concentration; a solution with a \(\mathrm{pH}\) greater than 7 (e) an acid that does not completely ionize when dissolved in water (f) a substance that forms after an acid loses an \(\mathrm{H}^{+}\)ion (g) an equilibrium constant for the ionization of an acid in water; a value that expresses the strength of a weak acid (h) a measure of the acidity of aqueous solutions; the negative logarithm of the \(\mathrm{H}_{3} \mathrm{O}^{*}\) concentration (i) a combination of a weak acid and its conjugate base (or a weak base and its conjugate acid) in similar amounts; when in solution, something that helps prevent large changes in \(\mathrm{pH}\) when small amounts of \(\mathrm{H}_{3} \mathrm{O}^{+}(a q)\) or \(\mathrm{OH}^{-}(a q)\) are added
