The purpose of this lab was to synthesize indigo and an azo dye and to determine how effective each dye was to dye different types of fabrics. 0.168g of 2-nitrobenzaldehyde was dissolved into acetone along with 25 drops of distilled water and NaOH to synthesize indigo. The solution was filtered‚ and the solid indigo was placed into the filter flask to reduce indigo to leucoindigo with 10mL of 3M NaOH. The flask was heated along with sodium dithionite and distilled water added to the flask. Afiber

Thousands of people across the world dye their hair; dating back all the way to 3400 B.C. when “people used extracts from plants or minerals that contained pigments like those of henna or black walnut shells”("History & Future Discovery of Hair Dye."). In 1932‚ hair dye was refined to create chemical reactions in the hair to change the natural structure and color of hair. Cosmetologists are near a plethora of chemicals every day that include carcinogens and mutagens they would never suspect

Purpose: The purpose of this lab is to find the amount of blue dye #1 in the blueberry pomegranate gatorade. Procedure: We created dilutions using stock solution(10mL stock/0 mL water‚ 8mL/2mL‚ 6mL/4mL‚4mL/6mL‚ 3mL/7mL‚ 2mL/8mL‚1mL/9mL‚ 0mL/0mL). Before we put each dilution in the SPEC 20‚ we put water in a cuvette and put it in the SPEC 20 so we could zero out the percent transmittance. We collected the percent transmittance of each dilution using the SPEC20 with a wavelength of 630nm.

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

spectroscopy create graph to determine the concentration of dye in a sport drink‚ by creating series of standard dilutions of an FD&C Blue 1 Stock solution and measuring the percent transmittance of each dilutions. Results in each dilutions will be use‚ to determine the linear function among various functions (T‚ T%‚ log T‚ - logT) For a Beer’s law calibration curve. The produce provides a model for guided-inquiry analysis of the concentration of food dye(s) in sports drinks and other consumer beverages.

Since the premiere of Ibsen’s A Doll’s House‚ much has been discussed regarding the final controversial scene. Why does Nora leave not only Torvald but her children as well? Many critics and theater-goers questioned the morality of the play’s resolution. In fact‚ some productions in Germany refused to produce the original ending. Ibsen acquiesced and grudgingly wrote an alternate ending in which Nora breaks down and cries‚ deciding to stay‚ but only for her children’s sake.A Doll’s house; a chance

While sitting in my daughter’s room in our home‚ I observed her play with her three baby dolls and her kitchen set which is against her wall by her princess vanity. My daughter is 5 years old and I quietly observed her on 3/17/17‚ roughly about 1 hour and 10 mins. My daughter had her pink and white chef outfit on‚ using it as she pretends to cook her “babies” something to eat on her kitchen set stove. I then asked several questions as I observed her playing with her toys. I asked her what did she
