Oxidizing agent

This will dissolve and oxidize copper into Cu2+. The solution was then heated to remove the brown NOx fume. This is necessary since NOx acts as an oxidizing agent and will oxidize I in the redox reaction to be observed. When all NOx fume is removed, H2SO4 was added and the solution was heated until white SO3 fumes appear. The addition of H2SO4 will drives off all nitrogen oxide gas that can interfere with the redox reactions. The SO3 vapor that is observed is an indication that all NOx has been driven off. The solution was cooled in ice bath and DI water is added, followed by the addition of NH3 drop wise. The purpose of this step is to create a slightly acidic to neutral solution, which is an ideal condition for the redox reaction as mentioned above. Addition of NH3 will form Cu(NH3)42+,a copper tetramine complex with a dark-blue color, indicating a slightly basic solution. Adding H2SO4…

in a biological system. These electrophiles and nucleophiles play an important role in maintaining redox homeostasis, they are also a component in signal modulations and cellular transduction in an organism; as such, upsetting this fine balance between reduction and oxidation can have deleterious effects in the body. Inversely as in high concentrations of reactive oxygen species, or oxidizing agents, having harmful effects in the body, the same can be said for its counterpart. If the…

of Cu(NO3)2: Reaction 1 of the experiment involved performing a redox reaction to create Cu(NO3)2. Immediately after HNO3 was added to the copper wire (Cu), the brown NO2 gas was emitted from the solution. As the copper wire dissolved, the solution green and eventually blue. Once the reaction was complete, the solution ceased to emit gas. It was evident that the reaction was exothermic since the beaker was hot, indicating that there was a release of energy in the form of heat. It was crucial for…

Synthesis of reactive iron Chemical reduction method of Ferric chloride by sodium borohydride following reaction (Eq.1), was used to synthesize ZVI [14]. 〖2FeCl〗_3+〖6NaBH〗_4+〖18H〗_2 O→〖2Fe〗^0+〖21H〗_2+〖6B(OH)〗_3+6NaCl (1) Ferric chloride hexahydrate solution was prepared by dissolving 5 g of FeCl_3.H_2 O (99.0%, Junsei Chemical Co., Japan) in 125 mL of deoxygenated deionized (DI) water. Moreover, 3.5 g of Sodium borohydride (NaBH_4, 98.0%, Sigma–Aldrich Inc., USA) were dissolved in 125 mL…

Oxyhemoglobin Dissociation Curve A oxyhemoglobin dissociation curve is a tool used to show the relationship between the saturation of oxygen and the partial pressure of oxygen. It directly tells us how a person own body is utilizing oxygen intake, how carbon dioxide levels are being regulated, as well as how efficient the hemoglobin in our body binds and release oxygen molecules to the appropriate tissues that require it. Normally the oxygen that our tissues need in order to function properly…

Flow batteries have been around since the 1970’s this technological advance in the field of energy storage and acts as a fuel cell which can provide a new and efficient energy supply. One of the biggest advantages of flow batteries is that they can practically in an instance recharge just by replacing the electrolyte liquid,while this happens it is recovering the spent materials for recharge. Several different flow batteries have been developed, including Redox, Hybrid and, Membraneless. The…

Purpose: By doing this experiment, students will properly complete a redox titration well also determining the amount of hypochlorite ions present in the commercial bleach given. Introduction: Commercial Bleach and other commercial products like hair colouring agents, contain oxidizing agents. Oxidizing agents are substances that remove electrons from one or more reactants and thereby oxidizes it, whereas reducing agents are substance that give electrons to other reactant. There is some…

addition of heat. As heat was added, the reaction was by definition considered endothermic. As no heat was added for reactions 1, 2, 4, and 5, they were considered exothermic. This was observed as a noticeable release of energy in reaction 1, where the release of heat increased the temperature of the solution. The release of heat energy in the other exothermic reactions wasn’t observed this clearly, but as heat wasn’t added, they were still considered exothermic. The first reaction was…

The Problem of Moral Agency in Hamlet In order to be a moral agent, a person has to have a good sense of self, they have to know exactly who they are and how they must act according to the decisions they make. In Hamlet, the moral task at hand is revenge for the murder of Hamlet the elder. The murdered King's son, also of the same name, must be the one to avenge the murder. Before Prince Hamlet finds out the true story behind his father's death, he has his mother's…

As Agent Smith tells Neo, "You have been living two life’s" (The Matrix). As Thomas, he's working for a software company and lives inside the matrix. As Neo, he is a computer hacker who wakes up in the real world. Neo is referred to as “the One”. “In Christian theology, Jesus Christ is the Messiah (Son of God, Son of Man, "Light of The World") who saves mankind from its sins" (John 8:12). In the Bible, Jesus dies on the cross, but later is resurrected and ascends to heaven. Christ translates…
