Lab Partner: Keren Appiahene Mussie Gide 10 September 2016 Experiment 2: Acid- Base Extraction Separation of an Organic Acid‚ a Base and a Neutral Compound Introduction: The extraction technique is often used in the organic lab to separate organic compounds from mixtures. One type of an extraction technique is the acid-base extraction‚ which is used to separate organic compounds from a mixture based on their acid-base properties.1 There are certain principles that must be taken into account when

The law that was specifically created to deal with encryption policy in the US was the Security and Freedom through Encryption Act of 1999. In an information security context‚ privacy is not absolute freedom from observation‚ but rather it is a more precise state of being free from unsanctioned intrusion. Another name for the Kennedy-Kassebaum Act is the Health Insurance

expanding the genetic alphabet although it has only ever consisted of four natural bases. The four natural bases generally base pair to form A-T and C-G; however‚ the authors created an organism that consists of those in addition to another base pair: X-Y. Considering the fact that X and Y do not typically occur in nature‚ the authors actually ended up creating a semisynthetic organism (SSO) that has an unnatural base pair (UBP) and may be able to create new life. The numerous past failed efforts

Acid-Base Strengths of Organic Compounds By: Chris Frankmore Due Date: February 15‚ 2011 Resonance Benzenesulfonic Acid Benzoic Acid Benzyl Alcohol Benzylamine P-Cresol P-Toluidine Acid/Base | Structure | pH | Why It is a strong/weak acid/base | Benzenesulfonic Acid | | 1 | This is a strong acid because it has a pH of 1. Another reason why this is a strong acid is that its conjugate base has strong resonance stabilization

Equilibrium and Acid Base Test Review: May 2012 Things to know: 1. Explain DYNAMIC EQUILIBRIUM. Why does a reaction at equilibrium look like it is NOT reacting? 2. Are all reactions equilibrium reactions? What assumptions do we make when we say that a reaction does NOT take place or that it is UNIDIRECTIONAL and goes 100% to completion 3. Be able to sketch a graph of the following (assuming that you start with all reactants and no products) : a. A reaction that really doesn’t do anything
