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

EVE-TEASING Among various social problems‚ eve-teasing has become a great threat to our social life. This acute problem has become a common affaire in our day to day life. Eve-teasing is a sort of euphemism in which the naughty‚ aimless young boys pass bad comments on the teenage girls to make them irritated or embarrassed. It is mainly related to women. Mainly the teenage girls are the victims of it. Some young boys with no study and work like to play tricks and jokes on the school going girls

Various aspects of police operations Jose Sanchez Cja/214 November 23‚ 2011 Francisco Juarez Various aspects of police operations Being a police officer is not as easy as we all think. There are many risks that police officers take by trying to protect our community. Some of this risks police officers take can even take them to dead‚ every year a lot of them get injured and some they are just killed from all over the world. Let’s begin with some as simple as a car crash‚ the police officers

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

consistency. Consistency requires minimal temperature sensitivity. For those who anticipate shooting in different climate settings‚ single-base propellants (also known as nitrocellulose) will have less performance variation with temperature fluctuation when compared to double-base powders. Hodgdon and Vihtavuori 100 series are great examples of single-base powders.

DKFLSDFKLFKJ | Acid-Base Titration. | kfjhdkjhvdkfj | | April Jowers | 12/19/2012 | DKFJSDKJFHDSKJHF | Introduction In this lab we will use basic titrating skills and techniques in order to titrate HCl. We will also be practicing how to prepare the solution. Using the titration data‚ we can practice our stoichiometric skills and also become more familiar with using lab equipment. Titration is the process of measuring the exact volume of a solution of known concentration that is

ACID / BASE BUFFER SYSTEMS Abstract A buffer solution is a solution that contains both an acid and a salt containing the conjugate base / acid in sufficient concentrations so as to maintain a relatively constant pH when either acid or base is added. In this experiment a selection of buffer solutions (Bicarbonate/carbonic acid)‚ Lake water and distilled water were obtained to compare their buffering behaviours when mixed both with an acid and a base. The results showed buffering capacities for
