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

To accomplish this‚ you should carefully analyze your organizational unit in regard to each of Deming ’s 14 points‚ examining each point individually and noting what your organizational unit is doing in response to each of these points. Based on your analysis‚ develop a plan to address any shortcomings in the quality effort. Include the plan in your paper. This

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

Purpose The purpose of this lab is to find the boiling point of the liquid and find the melting point of the solid. Procedure Boiling point: To find the boiling point of Isopropyl Alcohol I put about 1 mL of it in the test tube. Then I attached the thermometer to the test tube with a rubber band(make sure the thermometer bulb is lined up with the end of the test tube). After that I made a water bath with a beaker and put in the test tube with the thermometer. I then used a burner and a burner stand

Grade Point Average (GPA) Grade point average (GPA) is the measure of how well you are doing in your academic studies. At Costaatt‚ the academic grading scale goes from A-F with matching points ranging from the highest 4.0 to the lowest 0.0. This is a mathematical calculation that indicates where an average of grade falls on the scale. When calculating your GPA firstly multiply the amount of grade points achieved‚ by the amount of credits for each subject‚ and then divides the total amount of grade

This speech was intended to reassure the country that the war was being fought for a good cause and for peace in Europe after World War I. However‚ that was not necessarily correct‚ and later on caused more issues. The eighth point Wilson discussed was that France was invaded by Germany
