1 Chapter 14 - Acids and Bases 14.1 The Nature of Acids and Bases A. Arrhenius Model 1. Acids produce hydrogen ions in aqueous solutions 2. Bases produce hydroxide ions in aqueous solutions B. Bronsted-Lowry Model 1. Acids are proton donors 2. Bases are proton acceptors 3. H3O+ is called the hydronium ion C. Conjugate Acid-Base Pairs 1. A conjugate base is what remains after an acid has donated a proton a. Cl- is the conjugate base of HCl 2. A conjugate acid is what is formed when a base accepts a proton base acid acid base 3. HCl is a stronger base than H3O+ (H+) so the equilibrium lies far to the right D. Acid Dissociation Constant 1. ][ ]][[ HCl ClHKa -+ = a. water is not included because, in dilute solution, the concentration of

Chapter 1 Introduction and Review Organic Chemistry, 6th Edition L. G. Wade, Jr. Chapter 1 * Definitions Old: ?derived from living organisms? New: ?chemistry of carbon compounds? From inorganic to organic, vitalism and W?hler, 1828 => Chapter 1 Chapter 1 * Atomic Structure Atoms: protons, neutrons, and electrons. The number of protons determines the identity of the element. Some atoms of the same element have a different number of neutrons. These are called isotopes. Example: 12C, 13C, and 14C => Chapter 1 Chapter 1 * Electronic Structure Electrons: outside the nucleus, in orbitals. Electrons have wave properties. Electron density is the probability of finding the electron in a particular part of an orbital.

Chemistry 1210: Introduction to General Chemistry Dr. Gina M. Florio 20 Sept. 2012 Jespersen, Brady, Hyslop Chapter 5A Molecular View of Reactions in Aqueous Solution A solution is a homogeneous mixture in which the two or more components mix freely. The solvent is taken as the component present in the largest amount. A solute is any substance dissolved in the solvent. Definitions CH. 5.1 Example of a Solution Formation of a solution of iodine molecules in ethyl alcohol where ethyl alcohol is the solvent and iodine the solute: CH. 5.1 Crystal of I2 placed in ethanol: A solution of I2 in ethanol: Properties of Solutions: Qualitative Composition The relative amounts of solute and solvent are often given without specifying the actual quantities.
