That is, how could the colorless spots be located? (for paper chromatography)Thin layer chromatography experiment. Show calculations for the Rf of each spot you observed.
- How to determine which is the most polar and least polar in REVERSE PHASE thin-layer chromatography? Also is paper chromatography, a planar or a column and solid-liquid or liquid-liquid?Which of the following is not a method for measuring reaction rates? A) total pressure B) thin layer chromatography C) isometric barometry D) spectrophotometry E) gas chromatographyIn silica gel chromatography, which compounds elute first? A-The least polar B-Those with ionic functional groups C-Those with the lowest boiling point D-Those with the highest molecular weight E-The most polar
- 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?Distances traveled by the solvent is 3.2 First spot ( fluorene) is 2.5 Second spot distance equals 1.4 How can we calculate the Rf for the Chromatography experiment?How does increasing the polarity of the developing solvent affect the Rf of a compound on a silica gel TLC plate?
- The following Rf values were computed from a normal phase chromatography experiment. Arrange them from most polar to least polar. I - 0.25 II - 0.84 III - 0.56 IV- 0.67Why do the ‘% Area’ values on the HPLC not correspond directly to composition by mole?1. what do the different colors in the result of paper chromatography experiment indicates? 2. Why do the colors of the object in paper chromatogrpahy have different distance from the spot?
