Esterification Lab Introduction Esterification is an important part of organic chemistry that has many practical applications. Esterification can be used to make polymers. In most cases‚ esters are used for scents – they often smell fruity and sweet. In general‚ an esterification reaction results from a condensation reaction between a carboxylic acid and an alcohol. The carboxylic acid group loses an OH group‚ and the alcohol loses and H. For instance‚ the reaction between methanoic acid and methanol

PTC Testing Lab 11/12/13 Abstract: The main purpose of this lab is to determine that you have the dominant PTC gene or recessive PTC gene. PTC testing is a method used to test for a genetic trait. People who have dominant gene taste PTC (phenylthiocarbamide)‚ and people who have recessive do not taste PTC. This trait is passed genetically from parents to their children‚ so that if a person has the trait‚ then at least one of their parents had the trait as well (New York

The lab was to include a purpose‚ procedure‚ data/observations‚ all reactions and side reactions written out with qualitative data beneath each product and reactant except H20‚ and a summary. The purpose of this experiment is to observe the qualitative aspects of a series of reactions involving copper. Procedure 1.Measure about 1g of solid copper. 2.Place Cu in Erlenmeyer flask and place flask under fume hood. 3.Add dropwise 15M HNO3 until solid copper is completely reacted. 4.Place flask

Title: Preparation and isolation of an Ester Aim: To make an ester and purify it Background Theory: Esters are derived from carboxylic acids and alcohols with the presence of a catalyst. A carboxylic acid contains the -COOH group‚ and in an ester the hydrogen in this group is replaced by a hydrocarbon group of some kind. Sulfuric acid (H2SO4)is used as a catalyst for this reaction in order to accelerate the rate at which the product is formed. The general formula of an ester is RCOOR’ in
