Experiment VI: Oxidation of Isoborneol with Bleach Purpose: In this experiment‚ Green chemical procedures were applied to oxidize isoborneol to camphor using bleach (NaOCl)‚ rather than the tradition chromium-based oxidizing reagents. The camphor was then purified using the process of sublimation. Procedure: Using a 50-mL Erlenmeyer flask‚ 1.316 g (8.5 mmol) isoborneol and 1.0 mL (17 mmol) glacial acetic acid were stirred vigorously with a magnetic stir plate. A volume of 1.7 mL NaOCl

Analysis of Commercial Bleach AP Chemistry Introduction: Many commercial products are effective because they contain oxidizing agents. Some products that contain oxidizing agents are bleaches‚ hair coloring agents‚ scouring powders‚ and toilet bowl cleaners. The most common oxidizing agent in bleaches is sodium hypochlorite‚ NaClO (sometimes written NaOCl). Commercial bleaches are created by bubbling chlorine gas into a sodium hydroxide solution (remember this from your “funky redox rxns”?)

Analysis of a Commercial Bleach Purpose: The purpose of this lab is to determine the amount of sodium hypochlorite (NaClO) in commercial bleach. This can be done by forming triiodide ions. To make the measurement more accurate‚ starch was added to help determine the endpoint of the solution. The significance of this lab is that industry can use these techniques to determine the amount of NaClO in the bleach of the rival industry and improve it. Hypothesis: The hypothesis is that‚ an accurate

commercial stain removers. One bad thing about these commercialized detergents is that it contains substances which may be harmful to us and our environment. Melissa McCarty‚ ND‚ at the Bastyr Center for Natural Health outside of Seattle‚ says chlorine bleach and stain-lifting solvents produce harmful fumes‚ can irritate skin and eyes‚ and can be fatal if swallowed. She adds that researchers have linked the chemicals to cancer and reproductive disorders as well. The greatest risk‚ McCarty says‚ might be

Sodium hypochlorite‚ also known as chlorine bleach‚ soda bleach‚ or household bleach is a chemical with the formula NaClO. A common way sodium hypochlorite gets into the San Francisco bay is through daily household cleaning products such as laundry bleach. In a survey conducted by The Clorox Company‚ it was found that four out of five households use sodium hypochlorite bleach for their laundry. Since laundry detergent companies are not required to list every ingredient‚ customers are often not aware

Student Loan - Thesis Servicing? Help. I currently have a student loan from 1994 that I have not had to start repaying as I do not reach the earnings threshold. This year I have deferred again and have received a letter from the Students Loan company confirming my deferment. At the same time I have received a letter from Thesis Servicing who have taken over the servicing of these accounts‚ saying that they do not have a current direct debit instruction set up for me and that despite my deferment

involves two oxidation-reduction reactions to calculate the oxidizing capacity of a sample of unknown bleach. In order to determine the volume of Na2S2O3 added‚ students will conduct a titration of bleach with thiosulfate with addition of a starch indicator to find the end point of the titration. Moreover‚ the oxidizing capacity of bleach is calculated with the percentage by mass of NaOCl in the unknown bleach sample. The overall chemical reaction throughout the experiment will be balanced with the two oxidation-reduction
