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

Paper chromatography is one of the easiest methods of chromatography. It is a method of planar chromatography (stationary phase is in form of a plane). Paper chromatography follows the basic principle of chromatography‚ which states that substances or components are distributed in between the stationary phase and the mobile phase. It is an analytical technique‚ where only a small amount of a sample is used for separating and identifying its components. Like any other method of chromatography‚ paper

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)

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

Chromatography is a process used to separate mixtures. The word chromatography is derived from the Greek words ‘khroma’ and ‘graphein’ meaning ‘color’ and ‘to write’ or to represent. Although there are a couple different types of chromatography‚ in each case a substance is placed onto or into a medium and a solvent is passed through the test substance. In chromatography science‚ the solvent is called the mobile phase or the carrier fluid and the medium is called the stationary phase. There are four

EXPERIMENT 5: CHROMATOGRAPHY Abstract Paper Chromatography uses a chromatogram paper as its stationary phase and the solvent as the mobile phase. Retention factor is the ratio of the distance travelled by the sample to the distance travelled by the solvent. This experiment aims to separate organic compounds‚ to compute Rf values and to identify unknown compounds using Rf values. The ten samples underwent paper chromatography to determine the components of the unknown sample. The mobile phase allowed

spp and its application in dye decolorization Project supervisor: Dr. R. Masalu Lab scientist: Mr. Chuwa INTRODUCTION: Due to rapid industrialization and urbanization‚ a lot of chemicals including dyes are manufactured and used in day-to-day life. Dyes are synthetic and aromatic molecular structural compounds. According to their dissociation in an aqueous solution‚ dyes can be classified as acid‚ direct reactive dyes (anionic)‚ basic dyes (cationic) and disperse dyes (nonionic). They are used
