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

Essay On The Process Of Tie And Dye Clothes are very important to people. The type of clothes on wears is sometimes used to describe that person. People have different preference to clothes of various colours. Different cultures have different methods that they use to decorate their cloths. These kinds of decorations are part of their cultural symbols. Different culture will prefer certain colours or certain kinds of decorations. Long time ago people would use tree leaves to make the colours for

TITLE Crime and Dye Lab Special Projects 1 Martin Enem LAB SECTION: BB2 INTRODUCTION Light is usually viewed as a result of the heating of a substance. The higher the temperature at which the substance is heated‚ the greater the vibrations that lead to certain light intensity given off by the molecule. It is this same theory that suggests why steel glows red hot when heated to high enough temperatures. The process of light emissions can also be induces through other means. 1 One

think of when you think of tie dye? I know I automatically think of hippie’s in the 1960’s and 1970’s. Today‚ many of us who wear tie dye feel some connection with that peace loving hippie spirit! Ironically‚ did you know that the first tie dye was worn by Japanese warriors as early as the fifth century (www.peaceloveandtiedye.com)? Tie dye is something that has actually been around for centuries. There have been many changes in tie dye through out the centuries. Now tie dye has evolved into being part

Analysis 1. Examine the structures of the FD&C Red No. 40‚ Blue No. 1 and Yellow No. 5 dyes. What are the similarities and differences in the structures of the three dyes? a. Red No. 40‚ Blue No. 1‚ Yellow No. 5 contain carbon rings and NaSO3. Additionally‚ Red No. 40 and Yellow No. 5 are very similar‚ as they both contain one nitrogen double bond‚ a hydroxyl group‚ and no ions. Blue No.1 contains nitrogen and chlorine ions and N(C2H5)CH2. 2. In the Introductory Activity‚ the developing solvents

DATE: March 21‚ 2011 COURSE: BS Chemistry II APPROVED: ___________ PREPARATION OF AZO DYES ABSTRACT In this experiment‚ the azo dyes p-nitrobenzene azoresorcinol and methyl orange were prepared by the azo coupling reaction. The p-nitrobenzene azoresorcinol dye was prepared from p-nitroaniline and resorcinol. The diazonium salt formed was from the reaction of the cold solution of dissolved p-nitroaniline in hydrochloric

experiments carriedout for the degradation of fabric dyes from aqueous solution using Chara and Chara beads are discussed below.Various analytical techniques like UV-Vis‚ FTIR spectroscopy were used to confirm the decolorization as UV-Vis spectroscopy; FT-IR spectroscopy and toxicity bioassay were truly used [14]. Also‚ Fourier transform infrared spectroscopy (FT-IR) is widely used to confirm the product obtained after decolorization of dye degradation experiments [15]. It helps in determination
