It closes the circuit, allowing the current to flow throughout the cell. The current flows through the salt bridge because it has charged ions, commonly K+ ions and NO3- , which act as "current- carriers "

In an electrochemical cell what is the purpose of the salt bridge?
To maintain charge neutrality in each of the half-cells.
What is salt bridge?
A salt bridge is a device used in chemistry laboratories to connect the oxidation and reduction half-cells of a voltaic cell (galvanic cell).
A salt bridge is needed in an electrochemical cell to buffer provide ions behave as an electrode or complete the electric circuit?
A salt bridge will allow for the completion of a circuit in an electrochemical cell.
What could be observed if a cell is placed in salt solution?
hi!!! if a cell is placed inside a salt solution then cell boundary going for raptured due to the water molecules comes out from cell to maintain the cons. equilibria.
Which is formed when a standard hydrogen half-cell is connected with a salt bridge to a standard zinc half-cell?
This forms a galvanic (voltaic) cell (battery).
What salt bridge is used in a copper zinc electrochemical cell?
Potassium Chloride is the most common salt bridge for this cell Potassium Chloride is the most common salt bridge for this cell
What prevents charge buildup in a galvanic cell?

What is salt bridge and give its function in a galvanic cell?
Salt bridge is a U-shaped tube contains a gel permeated with a solution of an inert electrolyte such as Na2SO4. The ions of the inert electrolyte do not react with the other ions in the solutions and they are not oxidised or reduced at the electrodes. The salt bridge is necessary to complete the electrical circuit and to maintain the electrical neutrality in both compartments (by flow of ions).
Could the ions go to another side of the cell through the salt bridge?
The charge of the ions go to another side of the cell through a salt bridge, not the ions themselves.

A salt bridge will allow for the completion of a circuit in an electrochemical cell.
What is the function of a salt-bridge in an electrochemical cell?
The salt bridge allows cations to move in the galvanic cell. Electrons move from the anode to the cathode, leaving cations behind. The salt bridge allows for a balance of cations and anions to occur to continue the flow of electrons.
What prevents charge build up in galvanic cell?
A salt bridge
Would a galvanic cell work without a salt bridge?
The electrolyte of a commercial galvanic cell normally extends from anode to cathode without interruption by a salt bridge. A salt bridge is normally a teaching tool to help show that: 1. Galvanic half-cells do not produce voltage 2. Conductors and insulators are not necessarily salt bridges. An electrolyte must extend from anode to cathode before the galvanic cell can produce voltage. 3. The chemical composition of the salt bridge can differ from the electrolytes in the half cells. 4. Ions travel through the salt bridge between the cell's anode and cathode. Salt bridges raise more questions than answers. For example: 1. Can the difference between an electrolyte and a conductor be defined? 2. How do ions quickly move through a solid or a long electrolyte? 3. When salt bridge composition differs from the galvanic cell electrolyte(s), must the salt bridge chemically react with the galvanic cell electrolyte(s)? 4. Why does galvanic cell voltage remain nearly constant while anode to cathode distance doubles.
What is the function of a salt-bridge in an electrochemical cell to actually migrate ions from one half-cell to another OR the salt-bridge sucks up the ions from a half-cell to make the half-cell neut?
The salt bridge exists to provide the electrical connection between the two reaction vessels while keeping the two reactions separate. The salt bridge provides a path for the charge carriers from one half of the cell to the other half. They migrate along this path when the circuit is closed, driven by the attraction of the anode for electrons or electron-rich species, and the attraction of the cathode for positively charged ions.
What does a salt bridge do?
It prevents charges from building up in the solutions.
