  • Redox Experiment

    An oxidation-reduction, otherwise known as redox, is a type of reaction that involves the transfer of electrons between two reactants. These reactions were identified as a redox reaction because of how they turned into a different color, signifying there was a transfer of electrons which changed the physical appearance of the solution. In order for the reaction to be redox, a chemical substance has to be used up in the process and it has to create a new chemical substance. It also had to have a transfer of electrons between each other, if there is no transfer, then the reaction is not a redox chemical reaction. In reaction one, the magnesium reactant was oxidized because it lost electrons, whereas the oxygen reactant was reduced because the reactant had a gain of electrons. Reaction two’s magnesium reactant was reduced because it had a gain of electrons, while the water reactant was reduced because it lost electrons. The third reaction’s magnesium reactant lost electrons, so it was oxidized. The hydrochloric acid found in this reaction was the reactant that…

  • Rlaming Redox Equations

    STEPS IN BALANCING REDOX EQUATIONS 1) Assign the Oxidation Numbers The Oxidation Number (ON) of an element is its charge. It is the number of electrons an element contains. This would be our basis on whether the element gained or lost electrons in chemical reactions. We can say that an element is in its Oxidation State when the element already has a specific ON. Unlike with our previous examples, not all equations would already reveal the ON of each element. In actuality, equations would…

  • Oxidation And Redox Reaction Conclusion

    Oxidation occurs when an element loses electrons and reduction occurs when an element gains electrons. Oxidation and Reduction are processes that always work together, hence the term oxidation-reduction reaction or redox reaction. Oxidation is also the gain of oxygen and loss of hydrogen while reduction is the loss of oxygen and gain of hydrogen. Redox reactions occur in everyday life, it is a highly significant form of chemical reaction. Examples of real life redox reactions include:…

  • Experiment 5: Anions And Redox Reactions

    Experiment 5: Anions and Redox Reactions Introduction (a) Objectives General: To examine the importance of potassium permanganate as an oxidising agent and the strong powers of halogens in oxidation. Part 1 Determining the colour associated with a certain halogen by adding a sample of the halogen to cyclohexane and recording the colours observed. Part 2 Identifying a halogen referring to the colours recorded in part 1, by reacting the halogen with a halide and observing the colour present.…

  • Chronic Oxidative Stress Via Hydroxyl Radical And Redox Homeostasis Case Study

    Anthony Alvarado Bio 1A Chronic oxidative stress via hydroxyl radical and imbalanced redox homeostasis Redox hemostasis has been shown to be an important factor in the overall aging and neurodegeneration processes in mammalian models; such as, Alzheimer’s and Parkinson’s. As a result, redox homeostasis has been a key point of interest in current research. Redox homeostasis is the balance between electrophiles and nucleophiles in a system, more importantly in a biological system. These…

  • Listerine And Redox Distillation

    different percentage amounts of ethanol in them; Listerine, Terra Fresca Wine and the last is a mixture of ethanol and water that was made by me. The three different methods compared are the redox titration method which involves the oxidation of ethanol to ethanoic acid and then titrating the residue with sodium thiosulfate, which would then be used to calculate the number of moles of ethanol present in the original sample. The method of distillation involves heating the samples to the boiling…

  • Copper Content Of Brass Using Iodometry

    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…

  • Oxidation And Reduction In Chemistry

    Background research: Redox reactions includes the two reactions called oxidation and reduction. Oxidation is defined as the loss of electrons, loss of hydrogen and gain of oxygen. Reduction, on the other hand, is defined as the gain of electrons, gain of hydrogen and loss of oxygen. Oxidation occurs when there is an increase in oxidation numbers and reduction occurs when there is a decrease in oxidation numbers. Oxidation numbers are values assigned to an atom in a compound which measures the…

  • Difference Between Photosynthesis And Respiration

    high energy electrons, which passes through a series of reaction that generates ATP and reduced NADP (NICOTINAMIDE ADENINE DIPHOSPHATE) which are used to power a series of reactions known as the Calvin Cycle or the light-independent stage. Aerobic respiration requires oxygen and anaerobic respiration to occur in the absence of oxygen. Aerobic respiration is a series of redox reactions that can produce up to 36 molecules of ATP per molecule of glucose and the reduced coenzyme NADH (NICOTINAMIDE…

  • Spontaneity, Conductivity, Galvanic Cells And Lead-Acid Cells

    Exploring Electrochemistry Aim: The Aim of this experiment is to investigate electrochemistry including spontaneity, conductivity, galvanic cells and lead-acid cells. Spontaneous reactions will be explored by observing the two reactions below: Zn(s) + Cu2+(aq) →Zn2+(aq) + Cu(s) Zn2+(aq) + Cu(s) → Zn(s) + Cu2+(aq) Conductivity will be explored through measuring the conductivity of water and water with salts. A galvanic cell will be constructed to investigate the two halves of a redox…
