CHM 256: BASIC ANALYTICAL CHEMISTRY TUTORIAL 1: INTRODUCTION: ANALYTICAL CHEMISTRY 1. What is chemical analysis? 2. Differentiate between qualitative and quantitative analysis (Oct 2008‚ 2009‚ Dec 2009‚ Apr 2010) 3. Give 7 steps in performing any chemical analysis (Apr 2010) 4. Briefly explain how to prepare the following solutions: a) 1.0 L 10.50 % (w/v) aqueous CH3CH2CH2OH (answer : 105 g) (Oct 2006‚ Oct 2007‚ Oct 2008) b) 500 mL 2.0 M H2SO4 from a commercial reagent‚ at 90% (w/w) purity

As an aspiring Trauma Surgeon I must obtain a bachelor’s degree in an area such as pre medicine‚ biology or a related scientific discipline. After I must take the MCAT and complete four years of medical school and earn a Doctor of Medicine (M.D.). M.D. programs combine two years of laboratory and class work‚ followed with two more years of clinical clerkships. After completing my educational requirements‚ I will spend three or more years in a general surgery residency where I will complete surgery

PAPER AND THIN-LAYER CHROMATOGRAPHY Lab 47 Michael Stravino‚ CHM 2211L‚ June 3‚ 2012 Abstract Thin-Layer Chromatography and Paper Chromatography can be used to identify identical compounds‚ unknown compounds‚ the number of components in a mixture‚ as well as other important uses not explored in this laboratory. This experiment explores these techniques to identify an unknown amino acid by TLC and analyze food colors using paper chromatography. By using 2.0 mL of dimethoxyethane and 18 mL of

CHM 116 Lab Investigations of Buffers I. Purpose The purpose of this experiment was to get an understanding as to how to properly prepare chemical buffers. Also part of this experiment was to gauge the effectiveness of the buffers by measuring their pH levels in various titration solutions‚ using a pH meter. II. Procedure To start our experiment we had to prepare Buffer B‚ which was the .060 M Ammonia/Ammonium solution. Using 3.0 M ammonia‚ we had to calculate

1.1 The atoms‚ during bond formation‚ may lose or gain electrons (valence electrons) in order to achieve a stable state‚ or technically speaking‚ a stable electron configuration. Usually metal atoms lose electrons and non-metals gain electrons in order to achieve electron stability. When dealing with bond formation (Ionic bonding for example) we need to analyse the outer shell of the atom. Metals usually present 1‚ 2 or 3 electrons in their outer shell therefore they have to give them away to achieve

Statement of Awareness in the Differences in Child and Adult Prescribing ‘Only nurses with relevant knowledge‚ competence‚ skills and experience in nursing children should prescribe for children. This is particularly important in primary care (e.g. out of hours‚ walk-in clinics and general practice settings). Any one prescribing for a child in these situations must be able to demonstrate competence in prescribing for children and refer to another prescriber when working outside their level of
