Ink Chromatography Lab Background Information Paper chromatography is an analytical method that is used for separating and identifying mixtures of substances into their smaller parts. Paper chromatography works because the ink used contains several dyes (pigments) that when place on porous paper are dissolved in a solvent by capillary action. When the pigments (solutes) are dissolved in the solvent (water & alcohol mixture) they move through the paper at different rates depending on their

Organic Chemistry ACL 8 January 2015 Chromatography Chromatography is a physical method of separating substances based on their properties‚ by distributing their components between a mobile and stationary phase. Chromatography is useful for observing mixtures and solvents‚ since it can be used to determine the relative bond strength of various compounds‚ a substances phase‚ and it can also the identity of unknown substances. Chromatography allows for the separation of chemical mixtures‚ generally in

Chromatography (Greek for ‘colour writing’) is used to describe various methods applied to separate mixtures (referred to as the sample of the experiment) with great accuracy to analyze them. By using chromatography we can manipulate these to move at different speeds through the system‚ thus separating them. Chromatography is necessary in chemical industries‚ as well as bio processing companies. Chromatography can be: 1. analytical: used to measure ratios of analytes(substance in simpler forms)

Title:The Chromatography Process of Expo Markers Abstract:This experiment is to uncover whether or not the Expo Markers are homogeneous or heterogeneous mixtures. The experiment will conduct filter paper being slightly submerged in a container of water and inspected for pigmentation changes. In the experiment the pigments will rise up the filter paper once exposed to the water (solvent). After the experiment‚ it concludes that the mixture is a homogeneous mixture due to the chemical

OBJECTIVES: The objective of this experiment was to extract plant leaf pigments and determining them by using the Rf values obtained from the paper chromatography technique. The hypothesis of the experiment was that all of the five listed pigments would be present in the extracted plant leaf according to the Rf values. PROCEDURE/APPARATUS: The equipments used were a 18 x 150 mm test tube with stopper‚ graduated cylinders‚ Erlenmeyer flask‚ mortar and pestle‚ metric ruler‚ tall jar‚ acetone‚ tiny
