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

The Lagrange point phenomenon exists in any system wherein the gravitational fields of two large bodies interact to create five “sweet spots”‚ within which lies the exact centripetal force necessary for a smaller object to remain in a constant orbit with the larger objects. There are five Lagrange points within the Sun-Earth orbit‚ as well as five Lagrange points within the Earth-Moon orbit. These points will vary according to the mass of the two larger objects‚ as well as the distance between
