belts‚ caps‚ etc‚ are the most preferred clothing for today’s youth. This study discusses compositions and methods of reducing or preventing back staining of indigo dyes on the weft yarn and pocket of denim garments. The dye‚ as it is removed from the denim material‚ post treatment with cellulase or by a conventional washing process may cause ‘back staining’ or ‘redeposition’ on the denim material; e.g : re-coloration of blue threads and blue coloration of white threads‚ resulting in less contrast between

Barry Allahyar Dr. Dodd CHEM 2122 2010-09-16 Experiment 19: Fischer Esterification‚ Conclusion The objective in this experiment was to efficiently perform an Fischer esterification of 1-butanol and acetic acid to form water and n-butyl acetate‚ and to confirm the esterification using IR spectroscopy analysis. It was found that 0.734 grams of n-butyl acetate was formed with a percent yield of 61%. The product was confirmed using IR spectroscopy and boiling point confirmation. The reaction mechanism

techniques. Here they are; Simple staining: Only one type of dye used for simple staining and it stains all cells the same color. Creating contrast between cell and background to observe cell morphology is aimed. Differential staining: A differential stain uses more than one dye and stains different kinds of organism with different colors. Positive staining: If cell itself is stained it is called positive staining. It sticks with specimen and gives its color. Negative staining: If background is stained

Chemistry 1 February 3‚ 2014 Harvesting CaCo2 in a precipitate reaction results in less grams desired amount (2 grams) Abstract: The objective of this experiment was to synthesize 2.00 grams of CaCo2 for a hypothetical manufacturing company using the two least detrimental (in regards to health and the environment) and least expensive chemicals possible through a precipitate reaction. A precipitate reaction happens when cations and anions of certain aqueous solutions react and combine forming

The conventional method was conducted by placing 2.0641 grams of salicylic acid in a dry 125 mL Erlenmeyer flask. In a fume hood‚ 4 mL of acetic anhydride and 5 drops of concentrated sulfuric acid were added to the flask. The contents were swirled in the flask and then heated for 20 minutes in a hot water bath. After the 20 minutes were up‚ 10 mL of cold water were added in 1 mL increments. The flask was cooled for 10 minutes and occasionally stirred. The crystals that formed were collected via filtration
