Two isotopic compounds are produced in the synthesis of a new therapeutic drug, which must be separated by repeated chromatography cycles. In each cycle, the solution containing both compounds passes through a chromatography column with a length L = 45.0 cm containing N theoretical plates. The unadjusted relative retention is y = 1.098. Calculate the number of theoretical plates, N. in the column of length L. The observed resolution is 1.82 after 14 cycles. plates Calculate the height of an...
Two isotopic compounds are produced in the synthesis of a new therapeutic drug, which must be separated by repeated chromatography cycles. In each cycle, the solution containing both compounds passes through a chromatography column of length ?=45.0 cm containing ? theoretical plates. The compounds have an adjusted relative retention, α, of 1.093 and retention factors of 6.09 and 6.66 , respectively. Calculate the number of theoretical plates, ? , in the column of length ? . The observed resolution is...

HW #3 for Chem 318 Due: April 29, 2019 1. Solute A has a K 2.5 for an extraction between water (phase 1) and chloroform (phase 2). If 100 mL of a 0.01 fraction will be extracted? For the same solute and, what fraction will be extracted if 5 extractions wi 80 mL chloroform each are used (instead of one 400 ml extraction)? M solution containing solute A in water is extracted one time with...
2. If two different compounds have the same Rr value, how might they be identified using paper chromatography? 3. Why is it important to keep the spots on the paper as small as possible? 4. If the solvent pool at the bottom of the beaker touched the spots on the 1.5cm line, what would happen to the spots? How would you address this error? 5. If you were teaching a student how to do paper chromatography, what three pieces of...
