The idea
Cell notation lists the anode half-cell on the left and cathode half-cell on the right, phase boundaries as single vertical lines, the salt bridge as a double line.
In practice
Zn(s) | Zn²⁺(aq) || Cu²⁺(aq) | Cu(s) names a cell: zinc oxidizing at the anode, copper reducing at the cathode.
Where people slip
Students often mistake the single line for the salt bridge's double line.
