Review

Exceptional MCAT Prep Materials, April 28, 2002
Reviewer: A reader from IL United States This book contains all the info necessary to do well on the Physical Sciences section of the MCAT. Everything is presented very clearly and this book truly gives you an understanding of mcat chemistry. I recently took the April MCAT and I must say that this book and the Examkrackers physics made me feel like the PS was a JOKE! Their materials allow you to understand the mcat science conceptually such that no mcat item is EVER intimidating. Each lecture is complemented with a 30min exam where you can test the concepts as you review. (They're challenging though) Examkrackers all the way with no Imitations!!!

There are three definitions of an acid that you must know for the MCAT: Arrhenius, Bronsted-Lowry, and Lewis. These definitions are given here in the order in which they were created. An Arrhenius acid is anything that produces hydrogen ions in aqueous solution, and an Arrhenius base is anything that produces hydroxide ions in aqueous solution. This definition covers only aqueous solutions. Bronsted and Lowry redefined acids as anything that donates a proton, and bases as anything that accepts a proton. Finally, the Lewis definition is the most general, defining an acid as anything that accepts a pair of electrons, and a base as anything that donates a pair of electrons. The Lewis definition includes all the acids and bases in the Bronsted-Lowry and more. Lewis acids include molecules that have an incomplete octet of electrons around the central atom, like AlCl3 and BF3. They also include all simple cations except the alkali and the heavier alkaline earth metal cations. The smaller the cation and the higher the charge, the stronger the acid strength. Fe3+ is a common example of a Lewis acid. Molecules that are acidic only in the Lewis sense are not generally called acids unless they are referred to explicitly as Lewis acids.
