    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 sub...

    INTRODUCTION Isopentyl acetate, 'banana oil', is a naturally occurring compound that possesses a distinctive odor. It is found in bananas, as well as many other organisms. This experiment attempts to produce iso pentyl acetate by heating under reflux, which involves heating the mixture in a flask with a condenser placed vertically in the neck since any escaping vapours condense and run back into the flask, by combining iso pentyl alcohol with acetic acid and an acid catalyst. The product was iso...

    Titration Problem: When adding acids and bases what is the titration of the two Research: Amounts of reactants and products in a reaction are commonly investigated in two ways in the lab, gravimetrically (by mass), and volumetric ally (by volume and concentration). Titration is the name we give to the process used to determine the volume of a given solution needed to react with a given mass or volume of a sample. We will use the quantitatively study a neutralization reaction, in a neutralization...

    The Activity of Enzyme Catalase I. Introduction: What is an enzyme? It is! SSa protein serving as a catalyst, a chemical agent that changes the rate of the reaction without being consumed by the reaction!" (Campbell: Reece, 2002). Each enzyme acts upon a chemical substance called substrate, which fits into the active site (the portion of the enzyme that attaches itself to the substrate) like a lock and key, and is converted into the products during the reaction. Meanwhile the enzyme is released ...
