  2. Salt bridge - Wikipedia

    en.wikipedia.org/wiki/Salt_bridge

    In electrochemistry, a salt bridge or ion bridge is an essential laboratory device discovered over 100 years ago. [ 1 ] It contains an electrolyte solution, typically an inert solution, used to connect the oxidation and reduction half-cells of a galvanic cell (voltaic cell), a type of electrochemical cell .

    To maintain the salt bridge, His31 will attempt to keep its proton as long as possible. When the salt bridge is disrupted, like in the mutant D70N, the pK a shifts back to a value of 6.9, much closer to that of His31 in the unfolded state. The difference in pK a can be quantified to reflect the salt bridge’s contribution to free energy.

  4. Liquid junction potential - Wikipedia

    en.wikipedia.org/wiki/Liquid_junction_potential

    The most common method of eliminating the liquid junction potential is to place a salt bridge consisting of a saturated solution of potassium chloride (KCl) and ammonium nitrate (NH 4 NO 3) with lithium acetate (CH 3 COOLi) between the two solutions constituting the junction. When such a bridge is used, the ions in the bridge are present in ...

  5. Electrochemical cell - Wikipedia

    en.wikipedia.org/wiki/Electrochemical_cell

    In a full electrochemical cell, species from one half-cell lose electrons to their electrode while species from the other half-cell gain electrons from their electrode. A salt bridge (e.g., filter paper soaked in KNO 3, NaCl, or some other electrolyte) is used to ionically connect two half-cells with different electrolytes, but it prevents the ...

  6. Galvanic cell - Wikipedia

    en.wikipedia.org/wiki/Galvanic_cell

    A salt bridge is used here to complete the electric circuit. If an external electrical conductor connects the copper and zinc electrodes, zinc from the zinc electrode dissolves into the solution as Zn ++ ions (oxidation), releasing electrons that enter the external conductor. To compensate for the increased zinc ion concentration, via the salt ...

  9. Reference electrode - Wikipedia

    en.wikipedia.org/wiki/Reference_electrode

    5) Reservoir via which the second half-element of the galvanic cell should be attached. The connection can be direct, through a narrow tube to reduce mixing, or through a salt bridge, depending on the other electrode and solution. This creates an ionically conductive path to the working electrode of interest.
