Introduction: In reduction-oxidation reactions, electrons are transferred. In reduction, the electrons are lost. While in reduction reactions, the electrons are gained. Whenever reduction occurs, oxidation must occur as well and vice versa. Whichever compound is being oxidized or losing electrons is the reducing agent. The reducing agent causes another substance to be reduced. Similarly, whichever substance is being reduced or gaining electrons is the oxidizing agent. The oxidizing agent causes another substance to be oxidized. A cation is an ion that is positively charged. While an anion is a negatively charged ion. Different cations have different chemical behavior and characteristics. These chemical differences are helpful when identification becomes important because it allows different cation to be distinguished from each other. This is a notion that is vital to this investigation. A chemical company that is in charge of producing on-site test kits has hired the team of researchers to obtain information about different cations and how to identify them. They also want information on how to separate the different cations while present in solution and how to be able to confirm the identification of them. This requires that the team of researchers create a flow chart in order to safely remove certain cations out of solution. The cations that are present in the solution are Ag + , Ba 2+ , Fe 3+ , and Cd 2+ . The characteristics of these cations is summarized later on in the report. The characteristics that were recorded had to do with whether or not a reaction occurred and if a precipitate formed. This information would be vital to the team of researchers when it is time to create a flow chart

    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.
