Title Identification of Analgesic Compounds Using Thin Layer Chromatography Abstract The objective of laboratory experiment six was to identify an unknown analgesic tablet using Thin Layer Chromatography (TLC) analysis. The procedure involved preparing TLC plates‚ solubilizing standard analgesics (ibuprofen‚ aspirin‚ acetaminophen‚ caffeine) and the unknown in isopropyl alcohol (IPA)‚ and developing the plates in acetone. Rf values were calculated for each compound. The unknown tablet showed an Rf

Although the "new information" that changed Aberle et al.’s minds indicated that inbreeding was at least as dangerous as Bittles’s estimates imply‚ they rejected the possibility that primitive man recognized this danger. Law and instinct. In Sir James’s words‚ It is not easy to see why any deep human instinct should need to be reinforced by law. There is no law commanding men to eat or drink or forbidding them to put their hands in the fire. The law only forbids men to do what their instincts

Abstract Pigments extracted from different greens have different polarities and may be different colors. Mixed pigments can be separated using chromatography paper. Chromatography paper is able to separate mixed pigments due to their polarity and solubility. Pigments of chlorophyll a‚ chlorophyll b and beta carotene will be separated on chromatography paper because each has its own polarity and solubility‚ which results in different distance traveled up the paper. Beta carotene is non-polar so it
