Purpose: In this experiment, electrochemical cells will be created to study the voltage potential. The student will understand how E cell values are calculated and determined and, ultimately, the impact of concentration of voltage. This experiment will clarify how to combine elements and determine the reaction’s overall potential voltage charge. Introduction: Electrochemistry deals with electrical energy and chemical charges and the overall relationship between these two categories. Voltic Cells are used to create electrical energy for chemical reactions. Meanwhile, electrolytic cells are used to cause chemical reactions for the electrical energy. From previous experiments and understandings, it is understood that redox reactions occur with the transfer of electrons. Therefore, electrochemistry focuses on electrons. Electrons connect an entire circuit whether the circuit is for electricity or chemistry, the flow of electrons cause an energy supply. With Galvanic Cells, the anode is always written on the left side. Then, a double vertical line is drawn showing the difference between the anode and the cathoe that is written on the right side of this double line. Daniell Notation signifies that a salt

    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.
