  • Redox Equation Essay

    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 only be presented as is and we will be the ones assigning the ON. In order to properly delegate the ON of the elements or compounds, the following rules should be followed and observed. It is a general rule that the charges or the ON should be multiplied…

  • Redox Reaction Lab

    The purpose of the experiment is to perform a series of chemical reactions involving copper. The goal is then to perform precipitation, acid-base, decomposition, and redox reactions using the copper cycle. The mass of the copper was then analyzed using the percent recovery formula. Reaction 1: The Formation 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…

  • Redox Homeostasis Research Paper

    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…

  • 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.…

  • Lab Report: Redox Chemical Reactions

    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…

  • Iodometry Lab Report

    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…

  • Aerobic Respiration And Photosynthesis Essay

    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 ADENINE D. Aerobic respiration has four stages: Glycolysis, Pyruvate oxidation, otherwise known as the link reaction, the Kreb’s Cycle and the…

  • Trypan Blue Exclusion Lab Report

    toxicity whereas, the SDH leakage indicates a later onset of toxicity. The SDH leakage method requires the cell to have larger holes in the membrane to allow the sorbitol dehydrogenase enzyme molecules to leak out. This is because the enzyme molecules are much larger in comparison to metal ions. Menadione (MD) readily undergoes a redox cycle in hepatocytes because they have high metabolic activity. When MD was present…

  • Electrochemistry Lab Report

    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…
