WebJun 14, 2013 · This video is being submitted for the Khan Academy MCAT video competition to help students learn information covered in MCAT Foundational Concept 5, Content ... The Rf value of a compound is equal to the distance traveled by the compound divided by the distance traveled by the solvent front. Example 1: A solvent front traveled for 0.7cm on a thin-layer chromatography paper (TLC) while a compound traveled for 0.5 cm. Calculate the Rf value. Therefore, the rf value … See more In order to calculate the Rf value, we will need to understand the meaning of rf values. Rf is short for retention or retardation factor. We can define it as the ratio of the distance the spot moved above the origin to the … See more The rf values of a particular substance should be constant irregardless of the concentration of the analyte. However, sometimes the rf … See more raytheon employees
How do you calculate Rf values in chromatography? [FAQs!]
WebCalculate the Rf value of the red spot. GCSE Chemistry – Chromatography and Rf Values Answer: Rf value = distance travelled by the spot/ distance travelled by the solvent = ⅗ = 0.6 →What is Chromatography? Chromatography is a technique used to separate and identify the components of a mixture. WebThe Rf value is calculated by measuring the relative distance traveled by a particular organic compound with respect to mobile phase RF=Ds/Df divide the distance the solution … http://dept.harpercollege.edu/chemistry/chm/100/dgodambe/thedisk/chrom/wback3.htm simply hired huntsville al
