Question

$KCl$ is preferred over $NaCl$ for salt bridge.

• A. True
• B. False

Answer 1

The correct option is A

True

Transport number is the fraction of the total electrical current carried in an electrolyte by a given ionic species.

Transport number of $N{a}^{+}$ ions is about 0.40,while transport number of $K^{+}$ ions is about 0.49.Hence $KCl$ is preferred because it can maintain nuetrality in the system,for a long time operation $NaCl$ will cause imbalance of ions in the system.
