Column Chromatography of Plant Pigments Jaybee Balilea‚ Sharmaine Baysic‚ Maria Anjelette Patricia Belen 3Bio-7‚ Department of Biological Sciences‚ University of Santo Tomas‚ Manila‚ Philippines Abstract Column Chromatography is a form of solid-liquid adsorption chromatography and depends on the essential principles as does in thin layer chromatography. It was used in this experiment in separating and analyzing the different components of Capsicum frutescens (siling labuyo) with the use

STUDY GUIDE INTEGRATED SCIENCE 10 PLANT UNIT DO YOU/CAN YOU…. 1. Understand that both plants and animals (eukaryotes) undergo a similar process for cellular division/reproduction? Both plant and animal cells undergo mitosis and meiosis. In plants‚ there is an alternation of generations; the gametophyte generation‚ where haploid gametes (pollen and ovule; sperm and egg) are produced via mitosis. Then the sporophyte generation combines these two into spores via meiosis‚ resulting in a diploid

Chromatography Analysis of Black Pens to Determine Unknown Sample Purpose: Paper chromatography was performed on five different black pens‚ using four different solutions to determine which would be most appropriate to use on an unknown sample. Paper chromatography was then performed on the unknown sample to identify which pen was used to create it. Procedure: Each person participating in the analysis was assigned one solution to work with: V. Temple used distilled water‚ D. Sellers used

The History of Paint Pigments Chem 111-404 April 24‚ 2013 Introduction: This report expresses five different pigments that were formed during chemical reactions. Three out of the total five reactions went through a metathesis‚ or double-replacment reaction. A metathesis reaction can be defined as “a chemical reaction in which an element or radical in one compound exchanges places with another element or radical in another compound.” (Webster). The other two pigments underwent a neutralization

Separation of Mixtures Mixtures exist in many forms in the world‚ and if it were not for methods of separation‚ many of these substances would be meaningless to us. Separating mixtures is extremely important to human lives; for example‚ many people filter water so that it is safe for drinking. Mixtures contain two or more substances that are not in a fixed ratio‚ and while some mixtures‚ such as concrete‚ are useful‚ others including salt water‚ are not as useful to us. Filtration‚ distillation

Education Program CHROMATOGRAPHY (Adapted from: Forensic Science Activities. University of Colorado Boulder Hughes Initiative. .) DESCRIPTION: Students will use paper chromatography to separate ink molecules and identify the pen used on an unknown sample of handwriting. Students will graph and analyze data they collect using paper chromatography. PURPOSE/GOAL: Students will be able to: • Gain understanding of the purpose of chromatography. • Measure and graph pigment separation. • Use evidence gathered

Candy chromatography is a method of analysis of separating and comparing of dyes used in candies and food coloring. It is also a proven method to analyze candy and its complex mixture‚ without having to taste it. These complex mixtures can be separated back into pure substances. To find out the ingredients of a favorite candy‚ chromatography would help to define every ingredient found in the candy sample. The word chromatography is derived from the two Greek words‚ "chroma" meaning color
