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 …show more content…
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
