    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 objective of this experiment was to synthesize indigo and azo dyes and use them to observe their effectiveness in dying natural fabrics. The results of the experiment are summarized below. Weights Starting materials: • Aniline-3-sulfonic acid: 0.493 g • Salicylic Acid: 0.398 g Azo Dye: 0.515 g % Yield: (actual/theoretical) x 100 • Actual 0.515 g • Theoretical: o Aniline-3-sulfonic acid: (0.493 g/173.19g/mol) = 0.00285 mol o Salicylic acid: (0.398 g/152.15 g/mol) = 0.00262 mol o Limiting Reagent:

    The Beatles made it sound effortless when they came out with their hit song “Let it Be‚” but how simple was it truly to let it be? There was so much going on regarding disobedience‚ drugs‚ and combat. During the 1960s‚ President Johnson had declared war with Vietnam. Young adults in this time period insisted on resorting to different tactics of coping and began to follow the trend that bands and movies supported: drugs. With drugs came strange ways of life including their fashion choices‚ beliefs

    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.

    characteristics of the flow could be determined. The rock inside the stilling tank are to calm the inflow water so that there will not be any turbulence interfere with the experiment. The water inlet and outlet valve and dye injector utilized to generate the required flow. A dye injection system is installed on top of the header tank so that the pattern of the flow can be visualized. The characteristic of the flow is observed‚ there are laminar‚ transition and turbulent flow. The volume of water

    separate the Red 40 and Blue 1 dyes inside of grape flavored Kool-Aid. It was determined that the 5% isopropanol will remove the Red 40 dye from the stationary phase. The 28% isopropanol will remove the Blue 1 dye from the stationary phase. The more polar molecule is removed with the more polar mobile phase‚ the less polar molecule is removed with the less polar mobile phase. This is where the principle “like dissolves like‚” plays a factor in the separation of the dyes. Both molecules are relatively
