Conclusion: The purpose of this lab was to synthesize and purify aspirin. The theoretical yield was calculated to 3.766g. The actual yield of pure aspirin was 2.863g with a yield of 76%. The percent yield indicates that our synthesis was a success but the yield is low and indicates that some of the aspirin was lost during synthesis. Some reasons for loss can result from human error such as loosing product from sticking on the spatula and the Buchner funnel and several weighings. Also‚ when transferring

of the specialized underlying structures of these life-forms. In order for us to appreciate these special adaptation‚ we first need to know how a typical plant or an animal cell organelle behaves in different water and solute concentrations. In this lab‚ we will determine the effects of hypertonic‚ isotonic and hypotonic solutions on plant and animal cells. In general when an animals cell’s placed in hypertonic solution it shrivels; a plant cell on the other hand undergoes plasmolysis. When an animal

Toxicology Lab 1. In this investigation‚ a wide range of concentrations of Sodium Chloride (NaCl) solution were created and the effects that they had on radish seeds were tested. This ultimately created a doseresponse experiment in which it was detectable whether or not radish seeds were a reliable bioassay for the toxicity of NaCl. The goal of this experiment was to determine a correlation between toxicity and seed germination/radicle

CHEM 2303: ANALYTICAL CHEMISTRY II LECTURE 1 – INTRODUCTION‚ SAMPLE PREPARATION AND SPECTROPHOTOMETRY WHY STUDY ANALYTICAL CHEMISTRY? To gain a knowledge of the methods and strategies that have been developed to investigate the nature of the chemistry around and within us. To answer the age old questions: What is it? What is it made of? How does it work? We must learn the principles of chemical analysis and the array of strategies that have been developed to analyze chemistry. HOW DO WE ANALYZE

Decomposition of Sodium Chlorate to Create Oxygen Gas Introduction: There are several types of chemical reactions. Those reactions include synthesis‚ decomposition‚ single replacement‚ and double replacement. In this experiment‚ we will be decomposing sodium chlorate to create oxygen gas. In a decomposition reaction‚ a chemical compound is being separated into elements or simpler compounds. AB → A + B is a simple way of expressing what happens in a decomposition reaction‚ AB break down into A

Experiment 5 COMMON ION EFFECT MALUBAY‚ Justin Damian PADRILLAN‚ Hazel Rose CD2‚ Group 5 Ms. Sarah Sibug 6 April 2013 ------------------------------------------------- ------------------------------------------------- I. ABSTRACT The common ion effect occurs when a given ion is added to an equilibrium mixture that already contains that ion‚ and the position of equilibrium shifts away from forming more of it. This paper is a follow-up of the experiment which aims to determine the common-ion effect

CHEM 2213 Lab 25 Title: The Detection of Fats‚ Proteins‚ and Carbohydrate in Foods Purpose: The purpose of this lab is to perform several general tests which help in identifying fats‚ protein‚ and carbohydrates in food. Procedure: Part A- Tests for Detecting Carbohydrates In this part you will conduct the molisch‚ benedict‚ and iodine tests. Purple in the molisch test indicates a positive test. Benedicts test will result in a brick red/brown color for a positive test. For the iodine tests

Lab 5 The Diffraction Grating Chinua McDonald Objective: To measure the wavelength of light with a diffraction grating. Theory: The two types of diffraction gratings are the transmission and reflection gratings. They are made by ruling on a piece of glass or metal a number of evenly spaced lines with a fine diamond point. Diffraction phenomena can be analyzed in terms of Huygens’ principle‚ according to which every point on the wave front of a wave should be considered as a source
