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...

* To appreciate the importance of such separation techniques
* To apply different methods and techniques in separating components of mixtures
Recrystallization of Benzoic acid
Chemistry 204-002 Date: 4/9/2011 Hector Ortega
Recrystallization is a method used to purify compounds, and this is a very important procedure because compounds are naturally impure. Polarity and solubility play a big role in this experiment and these characteris...

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...
EXPERIMENT 2: Recrystallization and Melting Point Recrystallization (or Crystallization) is a technique used to purify solids. This procedure relies on the
fact that solubility increases as temperature increases (you can dissolve more sugar in hot water than in cold water). As a hot, saturated solu...

Some background info:
The Italian naturalist Lazzaro Spallanzani was one of the founders of modern experimental biology.
Lazzaro Spallanzani was born in Scandiano on Jan. 12, 1729. He entered a Jesuit college at the age of 15 and later studied law at Bologna, but very early he became...
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...
Separation of a Carboxylic Acid from a Neutral Compound by Extraction
Reference: Smith, Chapter 2 (Acids and Bases)
Carboxylic acids and phenols are two families of organic compounds that contain carbon, hydrogen and oxygen, and also react with water to yield an excess...
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.

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...
