a tube containing a conducting solution used to connect half-cells in a voltaic cell; it allows the passage of ions from one compartment to another but prevents the solutions from mixing completely.
A glass tube containing an ionic electrolyte which provides electrical connection between two half cells.
a tube containing an electrolyte that connects the two compartments of a galvanic cell, allowing ion flow without extensive mixing of the different solutions
a technique for isolating the reference element of a reference electrode from the sample solution by use of an intermediate solution containing non-interfering ions. Formerly a U tube filled with saturated KCl (often gelled with agar) was commonly used. In the double junction reference electrode, the outer filling solution serves as a salt bridge.
a conductor with ions as charge carriers
a porous barrier which prevents the spontaneous mixing of the aqueous solutions in each compartment, but allows the migration of ions in both directions to maintain electrical neutrality
a tube containing a relatively high concentration of an ionic salt such as potassium chloride
The salt bridge of a reference electrode is that part of the electrode which contains the filling solution to establish the electrolytic connection between reference internal cell and the test solution. Auxiliary Salt Bridge: A glass tube open at one end to receive intermediate electrolyte filling solution, and the reference electrode tip and a junction at the other end to make contact with the sample.
A tube (often filled with ion-laced agar) that allows two solutions to be in electrical contact without mixing in an electrochemical cell.
A U-shaped tube containing electrolyte, which connects two half-cells of a voltaic cell.
In protein chemistry, the term salt bridge or salt bond denotes a relatively weak ionic bond between positively and negatively charged side-chains of proteins. Salt bridges contribute to the stability of protein structure.
