Calculate the RF value for a spot in a TLC experiment if the solvent move 13.5 cm and the spot move 9.1 cm from the origin
Calculate the Rf value for a spot in a TLC experiment if the solvent moved 14.9 cm and the spot moved 9.5 cm from the origin.
At the completion of the experiment, a student measures the solvent front to be 55 mm from the baseline. If a component in the sample being analyzed generates a spot whose diameter spans from 34 to 36 mm from the baseline, calculate the Rf value for that component.
It is acceptable to draw the TLC spotting line with a pen as long as it is marked very lightly. True False
Why Rf value is important in Chromatography? Please shortly answer at your own words. Answer should be the point (specific 4-5 lines).
A student spots an unknown sample on a TLC plate and develops it in pentane solvent. Only one spot, for which the Rf value is 0.05, is observed. Is the un-known material a pure compound? What can be done to verify the purity of the sample?
A student spots an unknown sample on a TLC plate and develops it in dichloromethane solvent. Only one spot, for which the Rf value is 0.95, is observed. Does this indicate that the unknown material is a pure compound? What can be done to verify the purity of the sample?
If a single spot divides into 3 unique spots during a paper chromatography experiment, how many Rf 's will be calculated?
If the TLC plates had been developed in a more polar solvent, would retention factors on the whole be larger, smaller, or unchanged? Briefly (1 - 2 sentences) explain your reasoning
Can you DRAW a TLC plate in an elution chamber that shows 3 lanes each with one spot. Label the following in your drawing: Solvent front Origin Mobile phase Stationary phase Distances needed to measure Rf value for one of the spots
a pigment in the thin layer chromatography traveled beyond or farther than the solvent front. Therefore, the Rf value of that certain pigment is greater than 1. What does this mean to the experiment?
As solvent polarity increases, the Retention Factor (Rf) of compounds on the TLC plate increases. Group of answer choices True False
