Answer 2

$\huge{\underline{\sf{\red{Answer-}}}}$

Salt bridge is usually an inverted U-tube filled with concentration solution of inert electrolyte . An inert electrolyte is one whose ions are neither involved in any electrochemical change not they react chemically with the electrolytes in the two half cells generally inert electrolytes like KCl, KNO3, etc. Are used.

$\huge{\underline{\sf{\green{uses-}}}}$

• To connect the solution of two half cells and complete the circuit.

• To prevent transference of diffusion of the solution from one half cell to the other.

• it prevents liquid-liquid junction potential.
