Question

what is salt bridge plz describe ? give its two function ​

Answer 1

Hi Friends !!

Here is ur Answer !!

Answer:

Salt Bridge: A salt bridge is a U- shape containing concentrated solution of an inert electrolyte like KCl, KNO3, K2SO4 etc. or a solidified solution of those electrolytes in agar-agar solution and gelatin.

These inert electrolytes do not take part in redox reaction of the cell and even don't react with the electrolyte used.

Function: the main functions of a salt bridge are;

They allow the movement of ions from one solution to another without mixing of the two solutions and complete the electrical circuit. To maintain the electical neutrality of the solutions in the two half cells.

Answer 2

Salt Bridge Function

The main function of a salt bridge is to help maintain the electrical neutrality within the internal circuit. ... Salt bridge prevents the diffusion or mechanical flow of solution from one-half cell to another. It prevents or minimizes the liquid-liquid junction potential..

A salt bridge or ion bridge, in electrochemistry, is a laboratory device used to connect the oxidation and reduction half-cells of a galvanic cell (voltaic cell), a type of electrochemical cell. It maintains electrical neutrality within the internal circuit...

Salt bridge prevents the diffusion or mechanical flow of solution from one-half cell to another. It prevents or minimizes the liquid-liquid junction potential. (Potential arises between two solutions when they are in contact with each other). Salt bridge acts as an electrical contact between two half cells.
