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

OF THE STUDY Bilimbi or scientifically known as Averrhoa Bilimbi have dozens of native names. It is widely called as cucumber tree or tree sorrel in English but the tree itself is native to most tropical countries. Filipinos generally called it "kamias" and it is a widely known tree that can be found in most house backyards. Bilimbi is a fruit-bearing tree from the genus averrhoa plant family‚ a close relative of carambola. Bilimbi fruit are used in many medicinal purposes because of its high

Introduction The overall objective of this experiment is to determine the mass percent of NaClO‚ sodium chloride‚ in standard bleach. The purpose of part 1‚ is to standardize Sodium Thisulfate‚ Na2S2O3‚ with the primary standard Potassium Iodate‚ KIO3. The standardized Na2S2O3 will then be used in Part 2‚ to help determine the mass percentage of sodium chloride in bleach. The chemical equation used in standardizing sodium thisulfate is‚ IO3- (aq) + 5I- (aq) + 6H+(aq) ---> 3I2 + 3H2O followed by

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

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

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”?)

One example of an antimicrobial that we use in our home is bleach. Bleach contains the ingredient hypochlorous acid. This ingredient “causes bacterial proteins to unfold and stick to one another‚ making them nonfunctional

Feasibility of Chili (Capsicum frutescens) and Kamias(Hedychium coronarium) as Mosquito Killer Background of the Study: This study is done by the researcher to give importance to the chili and kamias fruit. Not just in food‚ butthe researcher wanted to produce a mosquito killer out of them. For all we know that chili has beentested and proven to be the one good ingredient in mosquito killer making and what if it is added by theacidic property of kamias fruit? The researcher wanted to know the effect

Analysis of Commercial Bleach Lab I. Purpose In this experiment‚ the amount of sodium hypochlorite in a commercial bleach will be determined by reacting it with sodium thiosulfate in the presence of iodide ions and starch. A solution of sodium thiosulfate of known concentration will be added to the bleach using a buret in a titration procedure. The disappearance of the dark blue color of the starch-iodine complex will signal the end point. II. Procedures Pre-Lab Questions 1. What is
