(N/A) In the symbolic representation of an electrochemical cell,the reactions of the anode (left side) and cathode (right side) half-cells are denoted by placing a single vertical line between the metal and the metal ion,or the ion and the metal,respectively.
Anode and cathode are represented on the left and right sides,respectively.
Negative $(-)$ and positive $(+)$ signs are denoted on the anode and cathode,respectively.
Two parallel vertical lines $(||)$ are placed to denote the salt bridge between these two half-cells.
If an inert electrode is used,it is denoted by symbols like $Pt$ or $C$,depending on the metal used.
Example-$1$: Symbolic representation of the Daniell cell: $Zn_{(s)} | Zn^{2+}_{(aq)} || Cu^{2+}_{(aq)} | Cu_{(s)}$
Example-$2$: Symbolic representation of a galvanic cell constructed with an inert electrode: $Pt_{(s)} | H_{2(g)} | H^{+}_{(aq)} || Cu^{2+}_{(aq)} | Cu_{(s)}$
