### Understanding Voltaic Cells: Cr|Cr³⁺ and Ni|Ni²⁺ Half CellsIn this lesson, we will explore the construction of a voltaic cell, with specific attention to an anode that is a Cr|Cr³⁺ half cell and a cathode that is a Ni|Ni²⁺ half cell. The half-cell compartments are connected by a salt bridge to maintain electrical neutrality. We will identify the half-reactions occurring at both the anode and the cathode, and then compile these into the overall cell reaction. Additionally, we'll discuss the migration of electrons and ions to understand the complete functioning of the cell.**Note:** Use the lowest possible coefficients. Be sure to specify states such as (aq) for aqueous or (s) for solid. If a box is not needed, leave it blank.#### 1. Anode ReactionAt the anode, where oxidation takes place, the reaction is represented as:\[\text{____} + \text{____} \rightarrow \text{____} + \text{____}\]#### 2. Cathode ReactionAt the cathode, where reduction occurs, the reaction can be described by the following equation:\[\text{____} + \text{____} \rightarrow \text{____} + \text{____}\]#### 3. Net Cell ReactionThe net cell reaction is a combination of both the anode and the cathode reactions:\[\text{____} + \text{____} \rightarrow \text{____} + \text{____}\]#### Electron MigrationIn the external circuit, electrons migrate from:\[\text{\_\_\_\_} \quad (\text{\_\_\_\_}) \quad \text{to} \quad \text{\_\_\_\_} \quad (\text{\_\_\_\_}) \]#### Ion MigrationIn the salt bridge, anions migrate to maintain electrical neutrality. They move from:\[\text{\_\_\_\_} \quad (\text{\_\_\_\_} ) \quad \text{to} \quad \text{\_\_\_\_} \quad (\text{\_\_\_\_})\]This understanding of half-reactions and ion migrations is crucial for grasping the fundamental principles of electrochemistry and the operation of voltaic cells.
