Respuesta :
Any voltaic cell must have the salt bridge. A tube containing an electrolyte solution, such as KNO3(s) or KCl, is used (s). The salt bridge's job is to maintain the solutions' electrical neutrality while allowing unrestricted ion passage between cells.
What is Salt-bridge ?
An electrochemical cell that uses a weak electrolyte and a salt bridge to connect the oxidation and reduction half cells. A junction that joins the anodic and cathodic compartments of a cell or electrolytic solution is referred to as a salt bridge.
- The U-tube is filled with a combination made by combining agar-agar or gelatin with a heated, concentrated solution of the electrolyte to create the salt bridge.
- The fluid subsequently solidifies as gel inside the U-tube as a result of the equipment being cooled. This keeps the fluids from mingling.
What is Voltaic Cell ?
An electrochemical cell called a galvanic cell or voltaic cell, respectively named after the scientists Luigi Galvani and Alessandro Volta, produces an electric current by spontaneous oxidation-reduction reactions.
