February 22nd‚ 2012 Abstract The purpose of the lab was to determine the order of reaction for the dye Red #40. By measuring the reaction rate between bleach and the dye‚ the order of the reaction was determined to be first order. Introduction The study of kinetics is important for studying the amount of time it takes for a particular reaction to reach completion. By comparing two solutions of dye that have different concentrations‚ the reaction rate can be experimentally found. At this point

Finding the rate law was the overall goal of the laboratory. When finding the wavelength of the Azo Orange II dye‚ the highest wave was the point used‚ 483nm. The plotted points of the different concentrations absorbance’s made sense to have a steady upward slope because the dye was diluted in steady increments from full to ¾ and so on. Beer’s law was used next to calculate the absorbance of they time over time as bleach was added. One the absorbance value was calculated‚ the concentrations were

KINETIC‚ THERMODYNAMIC AND ISOTHERM STUDIES ON THE REMOVAL OF MALACHITE GREEN DYE FROM WASTEWATER USING ALPC. ABSTRACT: The aim of the present work is to investigate the quantity of removal of Malachite Green dye from aqueous solution using Activated Los Pantanos De Villa Carbon (ALPC). Generally‚ dyes are used in chemical‚ textile‚ paper‚ printing‚ leather‚ plastics and food industries. The need for the treatment of dye contaminated waste water passed out from the industry. In this study‚ Los Pantanos

beaker the dye molecules moved slowly because molecules move slower when cooled‚ but there was still movement because molecules are always moving. The reason that the dye molecules move is because the dye is made of matter‚ which is made of molecules and molecules are always moving. The reason that the blue dye molecules clumped together in the cold beaker is because molecules attract each other. As the blue dye molecules spread out‚ the spaces between all of them got larger. The dye molecules spread

gets its glossiness by plunging it in myrobalan and milk mixture. Curves and motifs are then drawn with a pointed kalam soaked in fermented jaggery and water mixture. These layers are applied individually followed by application of natural vegetable dyes. After application of each colour‚ the textile is dried and washed. As a result‚ each cloth goes through about 20 washes. The specialty of Kalamkari paintings is that after the long tedious process‚ when the painting is completed‚ the finished products

The procedure provided was used with only one change and one correction. The procedure calls for 3 or 4 drops of water to dissolve the dye on the M&M candies but 7 drops were used for each pair of candies because there wasn’t enough water in 4 drops to efficiently dissolve the dyes; the YouTube video for this step from the procedure also showed an application of about 7 drops. The traced solvent front line in this case was not a straight line but a curve with a maximum on 3.2in and minimum on 2.48in

Abstract To determine the rate law with respect to bleach and blue dye‚ a series of graphic and algebraic manipulations were done on the data obtained in the kinetic trace experiment in order to determine the different components that made up the rate law. Using absorbance spectroscopy to monitor concentration over time‚ rate order of the dye was found to be 1st order through the integrated rate law and through the proportionality method; the order of the bleach was also determined to be 1st order

Spectrophotometry was used in the lab to determine whether non-magnetized zeolite‚ magnetized zeolite‚ or charcoal was the more effective sequestration agent for Procion Red Dye. A calibration curve was created with the known concentrations and the absorbances of the Procion Red Dye dilutions at λmax. The slope of the calibration curve was used to determine the concentration of the analytes. As a result‚ charcoal was shown to be the more effective sequestration agent. Introduction PAHs‚ polycyclic
