Chapter 19: Problem 5

What is the function of a salt bridge? What kind of electrolyte should be used in a salt bridge?

Short Answer

Expert verified
In an electrolytic cell, a salt bridge serves to complete the circuit, allowing ions to move between the anode and cathode compartments, and preventing these solutions from mixing. An electrolyte suitable for use in a salt bridge should be a salt that can ionize into cations and anions, which do not react with the anode or cathode solutions and have similar migration rates.

Step by step solution

01

Understanding the Function of a Salt Bridge

A salt bridge serves two main functions in an electrolytic cell. First, it completes the circuit by allowing ions to move between the anode and cathode compartments, thus maintaining electrical neutrality in the separate compartments. Second, it prevents the solutions in the anode and cathode compartments from mixing.
02

Identifying Suitable Electrolytes for a Salt Bridge

In a salt bridge, the electrolyte should be a salt that can ionize into cations and anions. The chosen salt should not react with the solutions in the anode or cathode compartments. Moreover, both ions of the salt should have similar migration rates to avoid a potential difference across the bridge.
