How does a variation in the concentration of metal ions of the cathode in a Zinc-Copper electrochemical cell affect the electrical potential?
Introduction:

In a highly technological and quickly developing society, it is imperative to innovation that basic components are understood and explored to further expansion and advancement. In order to understand how everyday necessities such as cars, computers, and cell phones are constantly powered, it must first be understood what is in a battery as well as what happens to the ions within the battery. This can be explained by electrochemistry and the reaction that occurs within a battery, which is induced and explored in this experiment. The reaction that occurs within a battery cell is an oxidation-reduction or redox reaction in which one substance loses electrons while another substance gains them . Oxidation refers to the loss of electrons, while reduction refers to the gaining of electrons . Redox reactions, or oxidation-reduction reactions are highly similar to acid-base reactions, especially in the way that it is a set reaction where there cannot be one reaction without the other . This experiment aims to understand this reaction by examining how a variation in the concentration of metal ions in the cathode that experiences reduction affects the electrical potential difference between a Zinc-Copper electrochemical cell. This will be tested by increasing the amount of Copper Chloride that is dissolved in water to increase…
