- -T-4 A B C 2. The TLC plate (left) shows three lanes; the lower dotted line is where the original spots were made and the upper dotted line is the solvent front. You may assume that the solvent was non-polar and the TLC material was silica. Explain, using intermolecular forces, to describe what's happening in all three lanes (A, B and C). Hint: Start with the question: "Which lane shows the more polar substance?"arrow_forwardAssuming that the path length of your cuvette is exactly 1.00 cm, calculate the molar absorptivity for each of your KMn04 solutions at the wavelength of maximum absorbance, and take the average value.

The mixture is diluted with 2+ water to a final volume of 50.00 mL. Assume that all the cobalt in the ore sample is converted to Co'(aq). a. What is the (Co] in the solution if the absorbance of a sample of the solution is 0.74? b. Calculate the number of moles of CoT(ag) in the 50.00 mL solution. 2+ C.

Or does the size of the spots not matter? b) Do separation of compounds on a TLC plate depends primarily on polarity, boiling point, molecular weight, melting point, or density?arrow_forwardWhat happens if your silica column runs dry during purification? Group of answer choices: You may have to purify again. Your column may crack. You have to add more solvent to keep it from cracking. All of the above. None of the above.arrow_forward
