Unformatted text preview: CHEM 2050/2130 Quiz 1 Review Sheet Review the front material we see in the lab experiments: the “big questions” about this quiz point to “why” and “what” questions: i.e. why do we use . . . . , or what is the purpose of . . . . Recrystallization: Characteristics which are desirable for a recrystallization solvent can be found in the beginning of the recrystallization experiment. We perform mixed melting points to ID the proper material and rules out incorrect materials. When using a Melt-Temp, the temperature rise in the melting range, do heat too quickly. The range of heating should be 3 – 5 degrees/minute. Extraction: Understand the basic idea of a distribution coefficient: In the expression K organic / water = [A] organic / [A] water is a measure of the tendency for the solute to reside in one phase versus the other and is equal...
