Methods and Materials involved A tablet is a mixture of active substances and excipients usually in powder form‚ pressed or compacted into a solid. The excipients include binders‚ glidants (flow aids) and lubricants to ensure efficient tabletting; disintegrants to ensure that the tablet breaks up in the digestive tract; sweeteners or flavours to mask the taste of bad-tasting active ingredients; and pigments to make uncoated tablets visually attractive. A polymer coating is usually applied

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

approximately 90 degrees apart. The grooves must be deep enough so that the zinc is exposed‚ but not so deep that the penny’s mass is greatly affected. 4. 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.

Date of experiment: September 3rd‚ 2013 Organic Chemistry II – CHLB330 Name: Symone MoxeyLab Partner: Lynden Cooper Isolation of caffeine from tea leave Abstract:- Introduction:- Caffeine is probably the most commonly used addictive drug. This drug is found in a number of things ingested by people. It belongs to a group of nitrogen bases called purines. Because caffeine possesses these base-like properties‚ it is described as an alkaloid. They usually taste bitter and often are physiologically

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
