State

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.

Show

Zn(s) | Zn²⁺(aq) || Cu²⁺(aq) | Cu(s) names a cell: zinc oxidizing at the anode, copper reducing at the cathode.

Watch for

Students often mistake the single line for the salt bridge's double line.
