Separating Acids and Neutral Compounds by Solvent Extraction Introduction The purpose of this experiment was to use solvent extraction techniques in order to separate a mixture consisting of a carboxylic acid (p-toulic acid)‚ a phenol (p-tert-butylphenol)‚ and a neutral compound (acetanilide). Extraction is the process of selectively dissolving one or more of the compounds of a mixture into an appropriate solvent‚ the solution that contains these dissolved compounds is called an extract (Manion

3/16 Chem 322 Friday Partition Coefficient (Extraction) Lab for Benzoic Acid Reaction Mechanism: Purpose: The purpose of this particular lab was to demonstrate the difference in separation of Benzoic acid in water and Dichloromethane. Also the difference in separation of Benzoic acid in bicarbonate and Dichloromethane. By calculating the partition coefficient for each of these separations‚ it became clear the differences in the separation of the aqueous and organic layers. Observations

Na+ H+ Wallert and Provost Lab Excel with hard work and inquiry Ammonium Sulfate PPT Protocol Theory and Introduction: Ammonium Sulfate Precipitation is a classic first step to fractionate proteins by causing perturbations in the solvent with respect to ionic strength. Historically‚ separation methods were limited and as a result precipitation methods were highly used with very fine cuts in ppt conditions. As more choices of inexpensive and quality resins are commercially available precipitation

Experiment 5: Shifting Equilibrium A solution is in equilibrium when the rate of forward reaction and the rate of reverse reaction are equal. This equilibrium may be disturbed when the concentration of the reactants‚ the concentration of the products or the temperature is changed. If the process involves gases‚ a change in pressure can also affect the position of equilibrium. The concept behind this is Le Chatelier ’s Principle which states that when a system is disturbed through application

Analysis of Alum AlK(SO4 )2 . 12H2O AP Chemistry Lab # 5 INTRODUCTION Every compound has a unique set of chemical and physical properties. To identify a compound with certainty‚ experiments have to be conducted in order to verify these properties. Such kind of analysis is usually performed when a compound is synthesized‚ and whether the compound is indeed the compound desired needs to be ascertained. The main purpose of the experiment is to analyze alum‚ AlK( SO4

Question 1: You have carried out an investigation into the pigments that make up chlorophyll. Use the chromatogram you obtained when carrying out this investigation. Clearly explain the separation technique of paper chromatography in terms of partition. Calculate the Rf value of one of the constituent pigments and compare it to the book value. A paper chromatography was used to separate the pigments that make up chlorophyll to analyse‚ identify‚ and quantify the components‚ using paper (stationary

Abstract: One of the primary considerations in preparing pharmaceutical ointments is the properties of different types of ointment base. The types of ointment bases used as vehicles for drugs are selected or designed for optimum delivery of the drugs and also to contribute emolliency or other quasi-medicinal qualities. Ointments properties vary since they are designed for specific uses‚ ease of application or extent of application. The purpose of the lab was to learn the difference between
