What is the use of salt bridge in a daniel cell?

Question

In a Daniel cell the solution in the two beakers are connected by a salt bridge. What is the role of that salt bridge? Explain with an example.

Answer 1

In a Daniel cell, the salt bridge allows ions to move between the zinc and copper solutions, keeping both solutions electrically neutral. It completes the internal circuit so that electrons can flow through the external wire, and it prevents the solutions from mixing directly while allowing the cell to produce electricity continuously.
