SDSU Chemistry the Effect of Solvent Polarity Questions

Question Description

I’m working on a chemistry writing question and need guidance to help me learn.

Questions for Data Analysis and Results

1. Discuss the effect of solvent polarity in TC. Specifically, how does solvent

polarity affect the migration of spots and their Re values? Refer to the class TLC

results.

2. Analyze your TLC results. How does the crude solid compare to the recrystallized

solid?

Calculate your percent recovery.

What is the main reason that we get less than 100% recovery in a recrystallization?

(Where is the greatest loss of solid?)

Once you dissolved your impure solid in a minimal amount of hot solvent, why was

it necessary to cool slowly?

6. If you took melting points, discuss what the results tell you.
