What is the purpose of a salt bridge in a galvanic cell?
Understand the Problem
The question is asking about the function of a salt bridge in a galvanic cell, which is a crucial component in electrochemical cells that allows for the flow of ions while maintaining neutrality in the cell. The salt bridge also helps in completing the circuit, allowing for the flow of electrons through an external circuit.
Answer
To maintain electrical neutrality inside the circuit of a galvanic cell.
The final answer is to maintain electrical neutrality inside the circuit of a galvanic cell.
Answer for screen readers
The final answer is to maintain electrical neutrality inside the circuit of a galvanic cell.
More Information
A salt bridge is crucial in a galvanic cell to maintain charge balance by allowing the flow of ions, which prevents the solutions in the half-cells from becoming electrically charged.
Tips
Common mistakes include thinking the salt bridge moves electrons (it moves ions) and not recognizing its role in maintaining charge balance to sustain the cell's operation.
