What is the role of a salt bridge in a Daniell cell?
Click For Summary
SUMMARY
The salt bridge in a Daniell cell serves to maintain electrical neutrality by allowing the flow of ions between the anode and cathode compartments. Potassium nitrate (KNO3) is commonly used in salt bridges due to its high solubility and ability to provide potassium and nitrate ions, which help balance the charge during the electrochemical reactions. The salt bridge completes the circuit by preventing the buildup of charge that would otherwise halt the flow of electrons.
