Crystallization and Melting Points Organic Chemistry 221 9/19/2012 Intro/Purpose: The purpose of this lab was to use crystallization to separate a compound from a solvent and be able to choose the best solvent to do so. Then identify an unknown and verify purity using melting points. Solubility contributes to crystallization; because a solute has lower solubility at lower temperatures‚ which makes the solvent separate from the solution as a solid. This process is important to understand because

Pol Pot‚ the leader of the communist party known as the Khmer Rouge ruled Cambodia from 1975 to 1979. He aimed to convert Cambodia into his vision of a communist agrarian society. However‚ in doing so he administered the deaths of more than two million Cambodians and under his rule Cambodians suffered harsh realities. Towards the end of his four years in power he left the country in turmoil as the economy was destroyed and the country regressed to an impoverished state as Pol Pot hindered any progress

The Empty Pot (China) BY royal proclamation‚ the Emperor of China announced a contest to decide the next heir to the throne. The Emperor was old and had no son‚ and because he had been a plant-lover for years‚ he declared that any boy who wanted to be king should come to the palace to receive one royal seed. Whichever boy could show the best results within six months would win the contest and become the next to wear the crown. You can imagine the excitement! Every

Lab #1: Melting Points of Organic Compounds Report Form May 15‚ 2014 1. A “Melting Point Range” refers to the range of temperature at which a solid melts into its liquid state. 2. Pure compounds have narrow or ‘sharp’ melting point ranges‚ 1°C or less if the compound is very pure. A less pure compound exhibits a broader melting point range‚ between 3°C to 10°C as well as a depressed or lower range. 3. Crushing the sample allows for greater surface area-to-volume ratio of the powder‚ this

Melting Point Determination and Thermometer Calibration Lab Background: The melting point of a substance‚ a solid in this case‚ signifies the temperature at which the first crystal starts to melt until the temperature at which the last crystal disappears is reached. That being said‚ melting points are expressed in ranges‚ am organic compound will have a sharp range depending on the purity of the compound. Impurity of an organic substance will register an abnormal melting point based on its

Organic chemistry 201 | Mixed Melting Points | Determination of an Unknown Solid | | [Type the author name] | 9/15/2011 | Purpose : The main purpose of this experiment was to identify an unknown compound/substance by performing multiple experimental melting point tests. Pure and impure solids were tested to see what affect pureness/impureness had on a melting point. Background: The melting point of a solid can be used to determine the purity of the solid. Pure samples usually have

Recrystallization and Melting Point of Benzoic Acid Organic Chemistry 1 10/4/12 Abstract Recrystallization was done to remove impurities from the sample. The percent recovery of benzoic acid during recrystallization is 23.02%. The difference between the pure and impure samples was observed by comparison of melting points. It was found that impure sample had a lower and wider melting point range of 120.1-122.2 (C). The pure sample melting point range was 121.3-122.5 (C). These ranges helped determine
