line representation of electrochemical cells

https://doi.org/10.1351/goldbook.09067
Notation giving electrodes, electroactive substances, and other relevant information for an electrochemical cell. The notation starts and finishes with an electrode. Phase boundaries are denoted with a solid vertical bar |, boundaries between miscible liquids by a vertical dashed bar ¦, and a liquid junction by double vertical dashed bars ¦¦.
Note: The potential difference of an electrochemical cell is measured between a metallic conductor attached to the right-hand electrode of the notation and an identical metallic conductor attached to the left-hand electrode.
Examples:
  1. Pt(s)|HA2(g)|HCl(aq)|AgCl(s)|Ag(s)
  2. Cu(s) | CuSOA4(aq) ¦ ZnSOA4(aq) | Zn(s)
  3. Cu(s) | CuSOA4(aq) ¦¦ KCl(aq,sat) ¦¦ ZnSOA4(aq) | Zn(s)
