Answer
Example: NaCl, KCl, KNO3.
Work Step by Step
A salt bridge acts as an electrical contact between half-cells and makes a complete circuit.
It balances the charge in the half-cells by the migration of it's ion.
It prevents the attainment of fast equilibrium in half-cells.
It minimizes the liquid junction potential in the half-cells.
It provides a continual flow of electrons.
Inert salts are used in salt bridges. Example: NaCl, KCl, KNO3.
