Tlc Lab Report 5 Study Guide Rated A+

Based on our experiments, which solvent mixture was most polar? {Ans: The ethyl acetate and acetic acid mixture.}Thin Layer Chromatography consists of three parts: The analyte, the stationary phase, and mobile phase. Match each of these terms to what it was in our experiment. 1. Mobile Phase 2. Analyte 3. Stationary Phase {Ans: 1. the solvent 2. one of the analgesics 3. silica}Of the solvents that we used in our TLC experiment, which is least polar? Hint: When a non-polar and polar solvent are mixed, the polar solvent dominates in the overall polarity of the solvent. {Ans: hexanes}Based on our experiments, which analgesic is most polar? {Ans: Acetaminophen}Match each concentration of acetic acid to its name. 1. Concentrated acetic acid that forms "icebergs" when cooled to its melting point below room temperature. 2. Dilute aqueous solutions of acetic acid. {Ans: 1. Glacial acetic acid 2. vinegar}Based on our TLC experiments, which analgesic is least polar? {Ans: Ibuprofen}Complete the sentences. 1. The least polar compound should have a(n) 2. The most polar compound should have a(n) {Ans: 1. larger Rf on a TLC 2. smaller Rf on a TLC}Chromatography (color writing) was originally developed
