Chapter II REVIEW OF RELATED LITERATURE AND STUDIES The Bilimbi tree is attractive‚ long-lived‚ it reaches 16 to 33 ft (5-10 meters) in height. The leaves‚ very similar to those of the Otaheite gooseberry and mainly clustered at the branch tips‚ are alternate‚ 12 to 4 inches (30-60 cm) long‚ with 11 to 37 alternate or sub opposite leaflets‚ ovate or oblong‚ with rounded base and pointed tip. Small‚ fragrant‚ 5-petalled flowers‚ yellowish-green or purplish marked with dark purple. The bilimbi

Redox Titration Analysis of a Commercial Bleach Purpose To perform a redox titration. To determine the amount of hypochlorite ion present in commercial bleach. Introduction Many commercial products‚ such as bleaches and hair coloring agents‚ contain oxidizing agents. The most common oxidizing agent in bleaches is sodium hypochlorite‚ NaClO (sometimes written NaOCl). Commercial bleaches are made by bubbling chlorine gas into a sodium hydroxide solution. Some of the chlorine is oxidized

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

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”?)

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

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
