    Discussion By using acid-base extraction techniques, a three-component mixture was separated into its individual components which included an acidic, basic, and neutral component as previously mentioned. A separatory funnel was the mechanism used to carry out this procedure. Its easy handling allowed for thorough mixing of the solution. It was equipped with a stopper which was opened to release pressure from inside the funnel caused by the heat from one’s hands and also the reactions taking place

    Acid Base Extraction The purpose of this laboratory assignment was two-fold, first, we were to demonstrate the extraction of acids and bases, finally, determining what unknowns were present. Second, we were to extract caffeine from tea. These two assignment will be documented in two separate entities. Introduction: Acid/base extraction involves carrying out simple acid/base reactions in order to separate strong organic acids, weak organic acids neutral organic compounds and basic organic substances

    Acid-Base Extraction Lab Experimental: Three grams of a mixture containing Benzoic Acid and Naphthalene was obtained and placed in 100 ml beaker and added 30 ml of ethyl acetate for dissolving the mixture. A small amount (1-2 drops) of this mixture was separated into a test tube. This test tube was covered and labelled as “M” (mixture). This was set to the side and used the following week for the second part of lab. The content in the beaker was then transferred into separatory funnel. 10 ml of

  • The Effect Of Acid Base Extraction On Organic Compounds

    982 Words  | 4 Pages

    Introduction Acid-base extraction is a very useful technique in organic chemistry. It is used to separate organic compounds from each other. The idea is that most of organic compounds will be more soluble in organic solvents than they are in water (1). The extraction, in its most basic form, will result in unequal distribution of solute between two immiscible (not forming one mixture when added together) solvents (2). Since both of the solvents are immiscible, two separate layers will be formed

  • The Effect Of Ph Solution Of Feed Phase On The Removal Efficiency Of Citric Acid

    1526 Words  | 7 Pages

    Figure. 7. Effect of pH solution of feed phase on the removal efficiency of citric acid Transport conditions: Feed phase: citric acid 10-2 M, pH 2-12. Stripping phase: deionized water, pH=6.8. Membrane: 12.60 cm2 of surface area, Calix[4]resorcinarene (0.15 g/g mixture of polymers), 0.03 ml 2-NPOE/g mixture of polymers. Values obtained after 5 days of experimentation. 3.8 Stability of PIMs In this study, one PIM was reused, whereas the feed and strip phases were replaced after one cycle with

  • Acid-Base Imbalance

    Acid-Base Imbalance Janet J Memoli Grand Canyon University NUR 641E September 30, 2015 Acid- Base Imbalance One of the basic concepts that new nurses need to learn is that homeostasis in the body is maintained by the acid base balance in the body. That concept is critical when looking at arterial blood gases. This can help guide the nurse to anticipate what the doctor will order and the education that she needs to give the patient and the family. This case study should help to illustrate

  • Chemical Kinetcs – the Hydrolysis of Pna Ester

    1424 Words  | 6 Pages

    molecules containing a group of atoms called an ester can be hydrolyzed by water to form a –COOH group (carboxylic acid) and an HO-- group (alcohol) as follows: RCOOR’ + H2O ( RCOOH + HOR’ This reaction is spontaneous for almost all esters but can be very slow under typical conditions of temperature and pressure. The reaction occurs at a much faster rate if there is a significant amount of base (OH-) in the solution. In this lab experiment, the rate of this reaction will be studied using an ester called

    them where: what is the difference between an acid and a base; what is pH; what is equilibrium, what is Le Châtelier’s principle; and what is oxidation. Here are some of the things that I learned in lesson 07.01 (Acids and Bases) and lesson 07.02 (Acid-Base Reactions). An acid is a substance that produces hydrogen ions, H+ or hydrodium ionsH3O+ in solution. There are three “kinds of acids”: Arrhenius, BrØnsted-Lowry, and Lewis Acid. An Arrhenius acid is a substance the increases the concentration

  • Essay On Titration Of Carbonate And Bicarbonate

    preforming a titration with the use of NaOH to convert HCO3- to CO2-3. • Calculate the composition of carbonate and bicarbonate in the solution. Introduction Acid-base titrations are common laboratory practices that are used to determine the concentration of either an acid or a base, by neutralizing the substance with a known concentration of an acid or base. Crude sodium carbonate, also called soda ash, is commonly used as a commercial neutralizing agent. In this experiment, we will determine the composition

  • Acid Base Balance

    Acid-Base Balance Kelly Heffron Grand Canyon University NUR-614 September 16, 2015 Acid-Base Balance The acid base balance is a homeostatic process that aides the body in maintaining a pH in the arterial blood between 7.35-7.45 (Patient, 2015). The body works together through multi-systems to ensure that acidity or alkalinity never take over within the blood. The purpose of the following paper is define the classification of the acid-base balance, define the factors from the case study,
