A single upright stroke, marking a phase boundary.
Also known as: Phase boundary bar, Single vertical line in cell notation, Interface bar
In electrochemical cell notation a single vertical bar is a boundary between phases where a potential difference arises. It is a compact drawing of an entire apparatus: the whole cell fits on one line, left electrode to right, with each bar an interface.
Denotes a phase boundary across which a potential difference exists, in the line notation for an electrochemical cell.
