WebThe aim of this experiment was to take a mixture of solid benzoic acid, P-nitroaniline, and biphenyl compounds and separate the individual components through organic extraction, based upon their acid- base properties. The acid (benzoic acid) reacted with NaOH to give a salt that moved from the organic phase to aqueous phase and thus was removed ... WebFor the calculations sheets, values highlighted in yellow ...

Solved 1. a) Why does biphenyl have a higher Rf value
WebApr 8, 2024 · A convenient way for chemists to report the results of a TLC plate in lab notebooks is through a " retention factor ", 2 or R f value, which quantitates a … WebC. A compound will have the same Rf value with all stationary phases. D. A compound's Rf value depends on interaction with stationary phase. E. An Rf value will always range between 1 and 2. D. A compound's Rf value depends on interaction with stationary phase. (Stationary phase = TLC plate) (mobile phase = solvent) Calculating Rf Values. chinese moon landing photos

Consider the function f (x) = ln (x). Show how to find the Taylor series expansion for the function f (x) about the point x = a. Then, find the numerical … WebPredict the relative R f values for the three compounds in the sample. Show answer. 6) Plate A, below, represents the TLC chromatogram of a compound run in hexanes. The same compound was then spotted on a large TLC plate and again run in hexanes. Which TLC plate, B, C, or D, correctly represents how far the compound would run on the longer plate? grand poo bear merch
