Lab #2 PHYSICAL SEPARATION TECHNIQUES Introduction

substance, we will be concerned, in this experiment, with the separation of a mixture into its components, not with the identification of the substances. Techniques used to separate mixtures rely on differences in the physical properties of the components. Techniques useful for the separation of mixtures include the following:

Experiment: Identification of Unknowns* Introduction

Experiment: Identification of Unknowns* Introduction: Along with synthesis and the examination of the reaction mechanisms, an equally important part of organic chemistry has to do with the characterization and identification of compounds, which may be encountered in sources ranging from a laboratory reaction to exotic tropical plants.

X-ray Diffraction (XRD)

Hanawalt: Hanawalt decided that since more than one substance can have the same or nearly the same d value, each substance should be characterized by it’s three strongest lines (d1, d2, d3). The values of d1-d3 are usually sufficient to characterize the pattern of an unknown and enable the corresponding pattern in the file to be located.

LABORATORY 1 Melting Points and Mixture Melting Points

Hoover apparatus for this experiment, so read this section carefully. Part A – Approximate Melting Point of Unknown Compound Place 2-3 mg of your unknown on a clean, dry watch glass. If the compound is not a fine powder, crush it with a spatula. Load a melting point capillary by pushing the open end of the tube into the powder.

Acetic Acid Content of Vinegar: An Acid-Base Titration

E10-3 Introduction Vinegar is an acidic liquid, which is made both naturally and synthetically, from the oxidation of ethanol, CH 3 CH 2 OH, in an alcohol-containing liquid such as wine, fermented fruit juice (e.g. cider) or beer. It has been used since ancient times as an important cooki ng ingredient, e.g. in salad dressings and on fish and ...
