Give the symbolic representation of the following half-cells (electrodes):
$(i)$ $Zn_{(s)} | Zn^{2+}_{(aq)} (1M)$
$(ii)$ $Cu^{2+}_{(aq)} (1M) | Cu_{(s)}$
$(iii)$ $Pt_{(s)} | H_{2(g)} (1 \text{ bar}) | H^+_{(aq)} (1M)$
$(i)$ $Zn_{(s)} | Zn^{2+}_{(aq)} (1M)$
$(ii)$ $Cu^{2+}_{(aq)} (1M) | Cu_{(s)}$
$(iii)$ $Pt_{(s)} | H_{2(g)} (1 \text{ bar}) | H^+_{(aq)} (1M)$
(N/A) The symbolic representation of half-cells follows the $IUPAC$ convention where the electrode is written on the left and the electrolyte on the right for oxidation,and vice versa for reduction.
$(i)$ $Zn_{(s)} | Zn^{2+}_{(aq)} (1M)$ represents an oxidation half-cell (Anode).
$(ii)$ $Cu^{2+}_{(aq)} (1M) | Cu_{(s)}$ represents a reduction half-cell (Cathode).
$(iii)$ $Pt_{(s)} | H_{2(g)} (1 \text{ bar}) | H^+_{(aq)} (1M)$ represents a standard hydrogen electrode $(SHE)$ acting as an oxidation half-cell.
