Zinc-Copper Electrochemical Cell Affect The Energy Potential

Improved Essays
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

Place 1 measuring boat onto scale and zero the scale. Using a scoopula, gently place small scoops of Zinc Chloride onto the measuring boat until reaching the desired amount of 1.5g. This should be the controlled amount fo Zinc Chloride throughout the experiment. Remember to carefully place the material onto the measuring boat for maximum accuracy. When desired grams of Zinc Chloride is obtained, take the boat off the scale and dump contents into one of the 80mL beakers with water. Place Zinc metal strip into the beaker and stir the solid content well for 10 seconds or when it has clearly dissolved. Attach one end of black wire onto the 1 lead and the other end onto the top of the Zinc material. Repeat steps 7-9 with Copper Chloride and the Copper metal piece. Attach one end of the red wire onto the 5 lead and the other end onto the top of the copper material. Rip a thin strip of paper from a paper towel and dip said strip into the Potassium Nitrate solution until the strip is fully submerged. Place one end of the drenched strip of paper, or ‘salt bridge’ into the Zinc solution, and another end into the Copper solution. The set up should look similar to the diagram

    The main purpose of this experiment was to create an activity series. As shown above, the metals, in order of ease of reactivity, with Magnesium at the top (Being the most reactive) and Silver at the bottom (Being the least reactive). This shows that magnesium is more likely to give up its electron that aluminum or silver. The elements located near the bottom to this series would not react with other metals. This was proven when silver was placed in various aqueous solutions and did not react with them.…

    The cathode, or air electrode, is a thin porous layer on the electrolyte where oxygen reduction takes place. The overall reaction is written in Kroger-Vince Notation as follows: Cathode materials must at a minimum, electronically conductive. Currently, lanthanum strontium manganese (LSM) is the cathode material of choice for commercial use because of its compatibility with doped zirconium electrolytes. Mechanically, it has a similar coefficient of thermal expansion to YSZ and thus limits stress build-up because of CTE mismatch. Also, LSM has low levels of chemical reactivity with YSZ which extends the lifetime of the materials.…
