Question

Transcribed Image Text:10:04
Description
1.An organic compound is made and needs separating
from the reaction mixture and impurities. The pure
organic product is more strongly adsorbed to the
stationary phase than the impurities and reaction
mixture. Will the pure product leave the column first or
last? Explain your answer?
2.Two pure organic compounds A and B are to be
separated using column chromatography. B leaves the
column first.
a) Which compound has the largest retention time?
Explain your answer.
b) Explain why compound B leaves the column first.
You must refer to both the stationary and mobile phase
in your answer:
3. How do we analyze colorless components by TLC?
4. Why do we use retention factor in TLC/paper
chromatography and retention time in GC?

The size of a molecule is a factor that can greatly affect solubility of ions. Which molecule is larger, acetone or water? How could this affect the solubility of Nat and CI" ions in each solvent? 3. It is very likely that the acetone partition still contained a fairly good amount of water (and that the water partition contained acetone). Only one of the three concentration units will be affected by the water in the acetone solution. Which one is affected? Explain why, and why the other two concentration units will be unaffected by the amount of water.arrow_forwardPlease help mearrow_forward
- Answer all questions pleasearrow_forwardIn Part 1 of the experiment, you will generate a calibration curve in order to determine el for this reaction. In order to ensure that the [Fe(SCN)2*] for these calibration solutions is accurately known, a large excess of SCN is used, so that the equilibrium for these solutions lies heavily to the products, and we can assume all of the Fe2* added becomes Fe(SCN)2*. In Part 2, you will observe solutions prepared with various initial reactant concentrations in order to determine Keg for the formation of iron(II) thiocyanate.arrow_forward
