Experiment 13: Synthesis of 1- Bromobutane An SN2 Reaction Theory: One of the methods of preparing alkyl halides is via the nucleophilic substitution reactions of alcohols. Alcohols are inexpensive materials and easy to maintain. However‚ they are a poor leaving group the OH group is a problem in nucleophilic substitution‚ this problem is fixed by converting the alcohol into H2O. Objective: The objective of this lab is to observe the synthesis of 1-bromobutane in an SN2 reaction‚ to see how

UNKNOWN SAMPLE #97 COMPLEXOMETRIC DETERMINATION OF WATER HARDNESS DR. BUDRUK CHM 152 LL SEAN MARKIS 4 FEBRUARY 2015 Introduction Using a Lewis base neutral molecule to donate electron pairs (ligands) to a Lewis acid metal ion center to form a single cluster (complex) ion. When the complex ions forms with a metal ion (chelation) the ligand used is called the (chelating agent). EDTA acts as a great chelating agent due to the Nitrogen and Oxygen donating an electron pair to the

Abstract An experiment is conducted to prepare soap and thus‚ to compare the properties of the prepared soap and synthetic detergents which are precipitation‚ emulsification and cleaning abilities. It can be concluded that soap has the properties if emulsifying oil whereas detergent has not. The abilities of forming precipitates can be seen clearly in soap solution whereas detergent forms no precipitates at all. The experiment is completed and successfully conducted. Introduction

EXPERIMENT SIX - ANALYSIS OF STOMACH ANTACID TABLETS Purpose In this experiment you will measure the amount of stomach acid consumed (or neutralized) by various antacid tablets (Maalox‚ Tums‚ Rolaids: no Pepcid or Tagamet!). If you have a favorite one‚ bring a package to the lab (one color only). Inside your stomach‚ excess hydrochloric acid is neutralized by the antacid. Different antacids use different metal hydroxides‚ such as Al(OH)3 or Mg(OH)2. The general formula for this reaction
