Purpose: The purpose of this lab is to identify redox reactions and oxidation strength and to understand what it means when a chemical reaction is visualized with redox reactions. Introduction: Oxidation-reduction reactions occur when electrons move from one reactant to another. Oxidation happens when there is loss of electrons and reduction occurs when there is gain of electrons. An oxidizing agent is the reactant that gains the electrons. The reducing agent is the reactant that loses the electrons. When discussing reactions, to determine which species is “most easily reduced” is the same as saying which species is the “strongest oxidizing agents.” The strongest oxidizing agent is the weakest reducing agent, while a weaker oxidizing agent produces a stronger reducing agent. When balancing redox reactions, it is important to make sure the number of electrons on the right side and the left side of the equation are the same. The half reaction approach separates the oxidation reaction from the reduction reaction and balances them separately. Safety/Hazard: Compound Name Molecular Formula and Weight Detail/Safety Hazard Zinc Zn – 65.39 g/mol Slightly hazardous.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
