PROPERTIES OF SOLUTIONS: Ch 7 – Acids and Bases References: - Chemical Principles, Steven S. Zumdahl, Fifth Edition, Houghton Mifflin Custom Publishing, Boston, MA - Professor Paul Mc Cord Notes, CH 302, University of Texas at Austin 1 Acids are proton donors; bases are proton acceptors. The composition of a solution of an acid or base always adjust so as to satisfy the values of the equilibrium constants for the proton transfer The Nature of Acids and Bases

First acid-base definition, Arrhenius : i) acid, is a compound that contains H and reacts with water to form H + ii) base, is a compound that produces OH - Bronsted-Lowry Acids and Bases : i) acid : proton (H + ) donor; ii) base : proton acceptor Strong acid : The proton transfer (proton donor) reaction goes to completion (Fully deprotonated in solution) Weak acid : A fraction of the acid molecules donate their protons (Partially deprotonated in solution) The strength of an acid depends on the extent to which it donates protons to the solvent.
