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

Organic Chemistry: CHP 225 Thomas Hsieh Experiment 2: Boiling Points o Date experiment was performed: September 16‚ 2011 o Objective: To determine the boiling point of organic compounds such as tert-butyl alcohol‚ sec-butyl alcohol‚ n-butyl alcohol‚ and an unknown. o Principle: Boiling point is the temperature at which gas and liquid phases coexist in equilibrium. At this temperature‚ the vaporization rate and the condensation rate are equal. The liquid and vapor reach a state of dynamic

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

Case Study on Deming’s Fourteen Points February 17‚ 2013 Quality Management is key for any organization to be successful. From the very bottom of an organization were someone is handling mail‚ to the CEO running the show quality management is key in all aspects and areas. Dr. W. Edwards Demings had a vision to transform organizations based on a 14 point plan. The goal of his theory is that the points be applied to any organization. In the end‚ the plan is to improve and control the quality in

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
