Oxidation of Borneol to Camphor Objectives: The purpose of this experiment was to use oxidation to convert (1S)-(-)-borneol into (1S)-(-)-camphor‚ which was done via the use of reagents such as glacial acetic acid and sodium hypochlorite and laboratory techniques learned in previous labs. Afterward‚ the final desired product was obtained‚ and to characterize and ensure the purity of the product‚ further lab techniques were implemented. Overall Reaction: 0 out of 10 Oxidation Reaction:. Mechanism:

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 I2 (aq) +

is a common enzyme that is found in almost all living organisms exposed to oxygen. Hydrogen Peroxide and Sodium Hypochlorite Hydrogen peroxide is in bleaches too‚ but only the mild ones‚ which is the non-chlorine bleaches. Since only hydrogen peroxide isn’t very strong‚ other products usually use other chemicals to make the reaction and results more effective‚ for example; sodium

was conducted. A change in the strip to a deep blue color would signal an excess of sodium hypochlorite reagent present. An excess is the reagent symbolizes the end of the reaction because there is no longer any reactant left to consume reagent. After the reaction was deemed completed‚ the product was isolated and purified by ether extraction‚ aqueous extraction and evaporation. To determine how sodium hypochlorite acts as an oxidizing agent‚ the starting diol and final product were characterized

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 to the hypochlorite ion‚ ClO-‚ and some is reduced to the chloride ion

Commercial bleaches are created by bubbling chlorine gas into a sodium hydroxide solution (remember this from your “funky redox rxns”?). Some of the chlorine is oxidized to the hypochlorite ion‚ ClO- and some is reduced to the chloride ion‚ Cl- (a disproportionation reaction). The solution remains strongly basic. The

Montessori way of teaching mathematic is truly a wonderful and interesting way to learn the concepts of mathematics. Mathematic is very important for our daily life. Mathematic relates to numbers and numbers are around us all the time‚ so it is very important to introduce numbers to the child at very early age‚ but before you introduce numbers it is important to lay a strong foundation of practical life activities and sensorial training to the child. Practical life activities allows the child to

Abstract: Aim: This in-vivo study was conducted to compare the effect of MTAD and 3% Sodium Hypochlorite on postoperative discomfort in patients indicated for pulp space therapy. Materials and Methods: A total of 60 patients from Department of Conservative dentistry & Endodontics‚ Peoples Dental College‚ Bhopal‚ indicated for pulp space therapy were part of this study. Patients were randomly divided into 2 groups. Group 1- 30 patients were treated with MTAD. Group 2- 30 Patients were treated with
