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

Jan 20, 2024 · A salt bridge is a device which acts as a junction that connects the anodic and cathodic compartments of electrochemical cells wherein weak electrolytes are used. Role in Electrochemical Cells. The role of salt bridge in Electrochemical cells is to: Maintain electrical neutrality within the internal circuit.
Jul 3, 2019 · A salt bridge is a connection containing a weak electrolyte between the oxidation and reduction half-cells in a galvanic cell (e.g., voltaic cell, Daniell cell). Its purpose is to keep the electrochemical reaction from reaching equilibrium too quickly.
There are several types of salt bridges: glass tube bridges (traditional KCl-type salt bridge and ionic liquid salt bridge), filter paper bridges, porous frit salt bridges, fumed-silica, and agar gel salt bridges.
Aug 29, 2023 · The salt bridge is a vital component of any voltaic cell. It is a tube filled with an electrolyte solution such as KNO 3 (s) or KCl (s) . The purpose of the salt bridge is to keep the solutions electrically neutral and allow the free flow of ions from one cell to another.
Oct 9, 2024 · Salt Bridge And Its Conditions. It maintains electrical neutrality in two compartments by allowing the movement of anions toward the anodic compartment and cations toward the cathodic compartment. It is a glass tube having KCl, KNO3, and ammonium nitrate in a gelatin gel or agar-agar paste.
The salt bridge consists of a concentrated, nonreactive, electrolyte solution such as the sodium nitrate (NaNO 3) solution used in this example. As electrons flow from left to right through the electrode and wire, nitrate ions (anions) pass through the porous plug on the left into the copper (II) nitrate solution.
