  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 .

  3. 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 ...

  4. Salt bridge (protein and supramolecular) - Wikipedia

    en.wikipedia.org/wiki/Salt_bridge_(protein_and...

    A salt bridge in T4 lysozyme between aspartic acid (Asp) at residue 70 and a histidine (His) at residue 31. The contribution of a salt bridge to the overall stability to the folded state of a protein can be assessed through thermodynamic data gathered from mutagenesis studies and nuclear magnetic resonance techniques. [13]

  5. Electrochemical cell - Wikipedia

    en.wikipedia.org/wiki/Electrochemical_cell

    An electrolytic cell is an electrochemical cell in which applied electrical energy drives a non-spontaneous redox reaction. [5] A modern electrolytic cell consisting of two half reactions, two electrodes, a salt bridge, voltmeter, and a battery. They are often used to decompose chemical compounds, in a process called electrolysis.

  6. Cell notation - Wikipedia

    en.wikipedia.org/wiki/Cell_notation

    In electrochemistry, cell notation or cell representation is a shorthand method of expressing a reaction in an electrochemical cell.. In cell notation, the two half-cells are described by writing the formula of each individual chemical species involved in the redox reaction across the cell, with all other common ions and inert substances being ignored.

  7. Reference electrode - Wikipedia

    en.wikipedia.org/wiki/Reference_electrode

    Insert a piece of silver wire into concentrated HCl then allow the wire to dry on a lint-free cleaning cloth. This forms an insoluble layer of AgCl on the surface of the electrode and gives you an Ag/AgCl wire. Repeat dipping every few months or if the QRE starts to drift. Obtain a Vycor glass frit (4 mm diameter) and glass tubing of similar ...

  9. Half-cell - Wikipedia

    en.wikipedia.org/wiki/Half-cell

    The electrochemical series, which consists of standard electrode potentials and is closely related to the reactivity series, was generated by measuring the difference in potential between the metal half-cell in a circuit with a standard hydrogen half-cell, connected by a salt bridge. The standard hydrogen half-cell: 2H + (aq) + 2e − → H 2 (g)
