Literal Meaning of Chromatogrpahy correct answers Color writing Chromatography correct answers A technique for separating compounds based on their interaction with two phases of an analytical system A technique used to separate complex mixtures on the basis of different physical interactions between the individual compound and the stationary phase of the system Separation Function correct answers The interaction of the particles between the MOBILE PHASE and STATIONARY PHASE allows them to...

Marquis Reagent - Turns purple with Heroin and Morphine, orange/brown with amphetamines Dillie-Koppanyi - Violet blue with Barbiturates Duquenosis-Levine - Purple with marijuana when chloroform is added Van Urk - Blue/purple with LSD (not appropriate for field tests) Scott Test - Color test for Cocaine. Adding cobalt thiocyanate turns solution blue, add hydrochloric acid and blue turns to pink, then add chloroform and it turns back to blue for positive result. Chromatography - Any of sever...

AAMC MCAT Practice Exam 1 Questions and Answers 2024 In the chromatography of the reaction mixture, water absorbed on cellulose functioned as the stationary phase. What was the principal factor determining the migration of individual components in the sample? A) Hydrogen bonding B) Solute concentration C) Stationary phase concentration D) Thickness of paper -Answer-A) Hydrogen bonding The answer to this question is A because the relative amount of hydrogen bonding to the stationary phas...

Title: Quantitative and Qualitative Analysis Purpose: The purpose of this experiment is to learn how to measure the amount of a substance that is present in a chemical compound. A metal carbonate will be analyzed to determine how much CO2 and moles of CO2 are lost. Another experiment will also look into how much water a hydrate loses and determine what type of hydrate it is. Paper chromatography will be used to determine the identity of chemical substances. Lastly, SEM/EDX will be used to d...
