The writers and poets of the Beat Self-organization, also called spontaneous order in the social sciences, is a process where some form of overall order arises from local interactions between parts of an initially disordered system.The process can be spontaneous when sufficient energy is available, not needing control by any external agent. Lab report # 2. Lecture and Lab Skills Emphasized Synthesizing an organic substance. Purpose/Introduction The process of recrystallization is an important method of purifying a solid organic substance using a hot solution as a solvent. Using an analytical balance (there are several top loader balances in the lab across the hall which will quickly weigh to 0.0001 mg), weigh 50 mg of caffeine and 37 mg of salicylic acid (both can be plus or minus 1-2 mg) and dissolve them in 4 mL of toluene in a small 25 mL Erlenmeyer flask by warming on a steam bath. Determining percent yield. Recrystallization depends greatly on polarity as the solvents used for recrystallization must have a similar polarity to the solvent used to dissolve it.
