2.2.7 Practice: ElectrochemistryAP Chemistry Sem 1Points Possible:25Name: Kayla JamesYou will need to use a calculator, a periodic table, and a standard reduction potential table to complete this activity. 1. Sodium can be extracted by heating naturally occurring salt until it is molten. An electrochemical process is then used to extract the sodium. Cl2is produced at the anode, and Na is collected at the cathode.a. Write the half-reactions that occur at the anode and the cathode. Identify each as either oxidation or reduction. (4 points) b. Based on these half-reactions, write the correct electrode potential levels at points Aand Bthe graph, assuming standard conditions. (2 points)on
c. Use the graph to determine Eºcell. (2 points)
