Benzoic Acid and Benzoates in Food, Drinks and Medicines
Benzoic acid and benzoates are common additives to food, drinks, medicines and cosmetics, and they also occur naturally in many plants. They are useful chemicals in manufactured products because they kill or inhibit both bacteria and fungi
I. Experiment 3: SEPARATION TECHNIQUES
* To learn different methods and techniques of separating components of mixtures
* To appreciate the importance of such separation techniques
* To apply different methods and techniques in separating components of mixtures
Crystallization of Benzoic Acid
The purpose of this experiment is to purify benzoic acid by crystallization.
1. 0.5g impure benzoic acid was placed in a 50mL Erlenmeyer flask. 15mL of water was added and the mixture was heated to a boil on a hot plate. 0.5mL of...

Benzoic acid is a derivative of benzene, also known as sodium benzoate or the salt of benzoic acid. The acid is a preservative and examples of foods that contain high amounts of this salt include sauces and pickles. In addition to its use as a food additive, manufacturers use benzoic acid...
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
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
The purpose of this lab was to separate and purify a compound. This was achieved using techniques that allowed the extraction of the acid, the isolation of the neutral compound and the melting point classification of the neutral compound to test the purity of the sample.

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
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
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.

States of Matter: Analysis of an Ocean Beach Mixture
To understand how matter is classified and how these classifications are related by analyzing the properties of several chemical systems.
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...

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...
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
