Transcript text: A voltaic cell must be split into two separate cells, an oxidation and reduction half-cells. The two half-cells must be connected by a $\qquad$ so ions can freely flow between the two half-cells to balance the charges or the voltaic cell cannot function. a. metallic wire b. salt bridge c. membrane

Solution

Solution Steps

Step 1: Understanding the Question

The question asks about the component that connects two half-cells in a voltaic cell to allow ions to flow freely and balance charges.

Step 2: Analyzing the Options

Option a: Metallic wire - This is used to conduct electrons, not ions.
Option b: Salt bridge - This allows ions to flow between the half-cells, balancing the charges.
Option c: Membrane - This can also allow ion flow but is not typically used in the context of a simple voltaic cell.

Step 3: Selecting the Correct Answer

The correct component that allows ions to flow and balance charges in a voltaic cell is the salt bridge.
