- During TLC, what is the stationary phase and what is the mobile phase?what chromatography seperation how is tlc part of itAlthough TLC is qualitative and tells you what is present in a given sample, it can also be used to determine where a compound might be lost: What samples could you test on a single TLC plate that might give you this information?
- 1. How does chromatography separate the components of leave samples? 2. Can you use chromatography to purify a mixture? why? 3. What is Rf value and its significance in chromatography?The following are the uses of TLC except Choices: Determine the number of components in a sample Detect a given compound or compounds in a very crude mixture Determine the concentration of certain components of the mixture Find suitable conditions prior to running a column chromatogram None of the aboveTLC relies on differences in non-covalent forces. Explain the role of these non-covalent interactions in determining the Rf value obtained.
- Explain why TLC cannot be used for some volatile low molecular weight substances such as toluene.Why chromatography is an important tool for analysis of organic compounds?A student performs a TLC experiment and at the end of the experiment, sees no spots other than the initial spot. What does this mean, and what should the student do to fix the problem?
