Objective: The objective of this experiment is to use acid-base extraction techniques to separate a mixture of organic compounds based on acidity and/or basicity. After the three compounds are separated we will recover them into their salt forms and then purify them by recrystallization and identify...

EXTRACTION AND CHARACTERIZATION OF PROTEINS
This experiment entitled “Extraction and Characterization of Proteins” aims to apply different methods of protein extracti...
If one component of the mixture has magnetic properties, you can use a magnet to separate the mixture. Cobalt, iron and nickel all have magnetic properties. Note that not all metals are magnetic and magnetism is not a method to separate metals from non-metals. Gold, silver and...
The purpose of this experiment is to become familiar with the separation of mixtures of solid and learn separation techniques based on the chemical properties of a substance.
1. Separating out the Iron
a. Use your digital scale to determine the mass of your weighing dish....

Extraction and Evaporation: Separating the Components of "Panacetin"
Submitted- July 17, 2012
The purpose of this lab is to investigate the composition of a compound suspected to be Panacetin, a type of pain-killer. Panacetin is typically made up of sucrose, aspirin, and acetami...
Lab #3 Separation of a Mixture of Solids
To understand the different separation methods and techniques that depend on the chemical properties of a specific substance. Also to become more comfortable with performing those actions of separation so I have them in the...
This lab experiment was conduct and taught based upon the primary instruction and introduction to mixtures. With this lab I was able to determine and execute the proper separation of a mixture of solids through various means, such as evaporation and filtration. Using these...
PRINCIPLES OF CHEMISTRY LAB I
Separation Of Mixtures
A mixture can simply be defined as a substance that is made up or consists of two or more elements and/or compounds that are physically combined but that have not reacted chemically to form new substances. A mixt...

Separation of a Carboxylic Acid, a Phenol, and a Neutral Substance
The objective of the experiment is to identify the three substances in the mixture and to determine the percent recovery of each from the mixture. The u...
Organic Qualitative Analysis
Organic chemists must regularly identify the compounds that are formed in chemical reactions or isolated from natural sources. Discovering the identity of an unknown organic compound requires ﬁnding which functional groups it contains and then determining...
Separation of Organic Compounds by Acid-Base Extraction Techniques
A commonly used method of separating a mixture of organic compounds is known as liquid-liquid extraction. Most reactions of organic compounds require extraction at some stage of product purification. In this exp...
Multi-Step Synthesis of Benzilic Acid from Benzoin
The main purpose of this experiment was to convert a secondary alcohol to a ketone, utilizing a mild and selective oxidizing agent. In addition, this converted alpha diketone was then subjected to rearrangement to a carboxylate salt, t...
Liquid CO2 Extraction of D-Limonene
This convenient, effective and inexpensive liquid CO2-based extraction of a natural product (D-limonene) provides an engaging example of natural products extraction using an alternative solvent (liquefied CO2). Because the procedure can be carried out in a poly...
