The U.S Constitution was written in 1787. The Founding Fathers “recognized that government depended on the consent of the governed” (Dye & Gaddie‚ 80). The citizens of the United States give the government permission to have a government. The Founding Fathers are very significant because they provided limits on the power of the majority and safeguarded the rights of the minority. The Bill of Rights also provides safety for the minority and does not allow the majority to exceed their power. The paradox

2: SYNTHESIS OF ORANGE II (2-NAFTHOL ORANGE OBJECTIVE 1. To produce dye based to the coupling of diazonium. 2. To understand the characteristic of dye orange II. INTRODUCTION The first dye was introduced by William Henry Perkin on 1856. It can be produced by the coupling of diazonium sulfanilic acid with nafthol in alkaline solution.. This was the common method used to produce dye nowadays. In this experiment‚ dye produced was the orange II. Azo compound is compound that contain azo group

the art of printing with vegetable dyes and mineral colours. Block printing‚ tie and dye work‚ heavily embroidered fabrics‚ motifs etc. are all included in Rajasthani textiles. This art of handblock printing‚ dyeing and painting separately or together to produce attractive fabrics and patterns is very ancient in India. It flourished in different parts of India and the differences lay probably in techniques‚ ingredients and equipment. The value of a natural dye was appreciated greatly by calico

the experiment‚ the stationary phase was the filter paper onto which the dye samples were dropped onto while the mobile phase was the solvent mixture containing ethanol and water which carried the sample dyes as the mixture went up the paper at different rates. These rates depend on the solubility and polarity of compounds in solvent. The objectives of this experiment are to compute the retention factor values of 6 sample dyes: methyl

hair coloring history came in 1863‚ when chemist Dr. August Wilhelm Von Hofmann reported the dye properties of paraphenylenediamine. His discovery led to the birth of the synthetic hair dye industry‚ and PPD still Dominates the field today. Hofmann was also known for his studies of organic derivatives of ammonia and for discovering the first unsaturated alcohol and several organic dyes. On the heels of Hofmann’s discovery‚ in 1867 London chemist E. H. Thullay and Parisian hairdresser

CHAPTER 1 Introduction Background of the Study Nowadays‚ most documents need to be printed. For most students and office workers‚ their homes are not complete without the printer. Owning this device is really just a necessary convenience in their everyday lives. However‚ despite the very high demand for printers‚ inks and paper in the modern world‚ it is overlooked that these materials are expensive to make. Printers and printer inks cost several hundred pesos and few people have the privilege

identify bacteria: acidic and basic dyes. Acidic dyes are so called because they consist of a salt that has a cation that transfers no color‚ but the anion portion is colored and does give off color. Basic dyes consist of an anion that does not give off any color and a cation that does stain biological samples. Examples of acidic dyes include acid fuchsin and eosin; examples of basic dyes include crystal violet‚ methylene blue and safranin. As a general rule‚ basic dyes are attracted to the surface of

Chromatography of Food Dyes Name: Cassandra DeVaux Date: April 17‚ 2014 Purpose: To learn how mixtures of compounds can be separated and what food dyes are found in certain foods Introduction: In this exercise we will separate food dyes from a variety of sources. We will first gather data on known dyes where we know how many substances make up the dye. Then we will collect data on some samples where we do not know the make-up. We will compare our known dyes with our unknown samples

by the time it took in seconds for the dye to reach the bottom of the glass. The rate of diffusion for the first experiment was 13cm/46sec or 0.28 cm per second‚ the second was 13cm/32sec or 0.41 cm per second‚ and the third was 13cm/42sec. or 0.31 cm per second. The average rate of diffusion was 0.33 cm per second. I hypothesize that the color of the dye could make a slight difference in the rate of diffusion because the molecules that make up the dye may be heavier or lighter depending on what
