Answer 2

A salt bridge is a u shaped tube attached with cotton plugs at each end .

• It is filled with a mixture of agar agar solution and  inert  electrolyte like

    KNO3,KCl,  

• It is placed inverted into these solution.

Function :

--->It helps  in completing the inner circuit

--->It prevents  the diffusion of electrolytic solutions in two half ells.

-->To maintain electrical neutrality of the solutions in the two half cells
