3.1 g.cm-3
2.5 mL
0.047 mol
Procedure
1.      Weigh out 0.2 g of fumaric acid and place it in a 25 mL Erlenmeyer flask.
2.      Add 2.5 mL of bromine stock solution.
3.      Heat the resulting solution in a boiling water bath for 12-15 minutes.
4.      If the solution becomes colorless add bromine stock solution to maintain a pale yellow to orange color.
5.      Cool your flask in ice and collect the product by vacuum filtration.
6.      Rinse the product with ice cold water.
7.      Allow the product to dry for 1 week.

8.      Then determine its yield and melting point.

The Kritios boy and Kroisos

-
Art is used as a way to express human’s creativity. Ancient Greece art paved the way for the Classical, Archaic and Hellenistic art. Art is very important to the Greeks, Greece have been making art from the earliest time until now. The Archaic period was at time between 700-400 BCE where abundant of Kouros (youth) sculpture were made. They were used as grave markings or sometimes representation of a god. These sculpture were mostly stick figures with no movement made of bronze. After the archaic period, it was the classical period. Classical art represents the perfection of the human body. Many art sculpture represent at transitional art with features that are unique to two different time periods. The Kritios boy is from the late archaic and early classical. It is a standing sculpture of a nude man at 2’10’’ tall from 480 BCE. This represent a transition from the archaic to classical period. You can see that the artist understand the musculature of the boy. Where the abdominal muscl...

Observation 1.        After poring the water on the Biphenyl the biphenyl raised to the top of the water. 2.        The methyl acid took about 20 seconds to completely dissolve in the methyl alcohol. 3.        When ever the water and the alcohol were insoluble two layers were formed. Part A Water Methyl Alcohol Hexane Benzophenone Insoluble Soluble Partially Soluble Malonic Acid Soluble Soluble Insoluble Biphenyl insoluble Partially soluble Soluble Part B Alcohol Octanol Insoluble Soluble Butanol Partially Soluble Soluble Methanol Soluble Soluble Part C Water Hexane Ethyl Alcohol Miscible Diethyl ether Immiscible Methylene Chloride Immiscibl...

Preparation of Dibromosuccinic Acid- Post Lab 9

-
Observations 1.       Within 5 minutes the color of the solution starts to become colorless. 2.       We added around .5ml of the bromine stock solution to the solution while it was on the water bath. 3.       The product of this experiment was in the vacuum filter for 20 minutes. Data Fumaric acid: 0.19 Bromine: 2.7 ml Final weight of Fumaric acid: .59g Theoretical yield: 0.0028 mol x 275.88 g/mol = 0.77g Percentage yield: .59g/0.77g x 100%= 76% Melting point 250-255 ◦C Question Which stereoisomer of dibromosuccinic acid (racemic melting point = 170 o C, meso melting point = 290 o C) did you obtain? The stereoisomer of dibromosuccinic is Meso. The melting point of our experiment product is between 250-255 ◦C. It is not exact meso melting point however, it is closer to meso than racemic melting point.
