What is salt bridge and write its function Class 11?

The functions of the salt bridge are. A salt bridge acts as an electrical contact between the two half cells. It prevents the mechanical flow of solution but it provides a free path for the migration of ions, to maintain an electric current through the electrolyte solution. It prevents the accumulation of charges.

What is salt bridge and its function Class 12?

Salt bridge is an inverted U-tube like structure. The tube is filled with concentrated solution of an inert electrolyte. It completes the electrical circuit as it connects the electrolytes in the two half cells. It avoids the chances of diffusion of solutions between the half cells.

What are the main functions of a salt bridge?

Salt Bridge Function 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.

What is the purpose of a salt bridge?

The purpose of a salt bridge is not to move electrons from the electrolyte, rather it’s to maintain charge balance because the electrons are moving from one-half cell to the other. The electrons flow from the anode to the cathode. The oxidation reaction that occurs at the anode generates electrons and positively charged ions.

What are the basic properties of salt bridge?

The salt bridge usually consists of a strong electrolyte which is further made up of ions. For example, AgNO 3, KCl, etc. Salt bridges are generally used in a galvanic cell such as a voltaic cell or Daniel cell. The main function of a salt bridge is to help maintain the electrical neutrality within the internal circuit.

What is the use of the salt bridge?

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