A student investigates a series of compounds in a thin layer chromatography experiment. The student has a sample of three organic compounds labeled A, B, and C as well as an unknown compound. The student performs the experiment as shown on the left above and gets the results shown on the right. What organic compound is in the unknown sample?
The unknown sample gives a single spot that has migrated to the same amount as Sample C.
Compare your answer with the correct one above
Which of these solutions can be separated via chromatography?
Chromatography is the physical separation of components of a mixture. Answers b and c can be separated by chromatography due to their homogeneous nature. The soil and water example would be separated by filtration.
Compare your answer with the correct one above
Which of the following would most likely form a homogeneous solution?
Like dissolves like. The NH4Cl and water mixture involves an ionic solid and a polar solvent. Examples a and b involve mixing polar/non-polar solvents and ionic and non-polar solvents.
Compare your answer with the correct one above
If 50g of NaCl are dissolved in 5 L of water what is the solute and what is the solvent?
The solvent is what you the most off. In this case water is the solvent and sodium chloride is the solute.
Compare your answer with the correct one above
What would be the best solvent would you choose to dissolve C31H64?
C31H64 is a non-polar substance and would dissolve best in a non-polar solvent like Toluene.
