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

It has better qualities than ethanol‚ but is still more expensive to produce‚ which is holding it back. Source 8 states‚ “If you compared ABE (acetone‚ butanol‚ ethanol) yield to that of the yeast ethanol fermentation process‚ the yeast process yields 2.5 gallons of ethanol from a bushel of corn; with concentrations of 10-15% it becomes very clear why ethanol is considered a better alternative fuel

Clean the top and bottom surface of the penny with steel wool until it’s shiny. Rinse the penny in acetone and dry it on paper towel. 5. Determine the mass of the penny on the balance‚ and record the mass in the table on the bottom of the page. Removed the penny from the balance using tweezers and place it in its beaker. 6.

Copper-Iron Stoichiometry Lab Report 10/3/12 Abstract: The lab performed required the use of quantitative and analytical analysis along with limiting reagent analysis. The reaction of Copper (II) Sulfate‚ CuSO4‚ mass of 7.0015g with 2.0095g Fe or iron powder produced a solid precipitate of copper while the solution remained the blue color. Through this the appropriate reaction had to be determined out of the two possibilities. Through the use of a vacuum filtration system the mass of Cu was

CHAPTER I INTRODUCTION Pollution is one of the main problems the world faces today. One of the reasons is the overload of non-biodegradable objects like plastics‚ cans and Styrofoam. The invention of plastics and Styrofoam made a huge change in our society and it helped us in many ways. But it is also one of the main pollutants that destroy our planet. Because of these we devised a way to recycle used Styrofoam‚ and this is to make glue out of it. This glue can help reduce the number of Styrofoam
