Cell notations

Definition

Cell notation is a shorthand representation of a galvanic cell, showing the components of each half-cell and their arrangement. It typically follows the format: anode | anode solution (concentration) || cathode solution (concentration) | cathode.

5 Must Know Facts For Your Next Test

1. Cell notation separates different phases by a single vertical line '|' and different half-cells by a double vertical line '||'.
2. The anode (where oxidation occurs) is written on the left side, and the cathode (where reduction occurs) is on the right.
3. Concentrations of aqueous solutions are included in parentheses after the chemical formula, e.g., Cu^2+(1M).
4. If gases are involved, they are represented with their partial pressures in parentheses, e.g., H2(g, 1 atm).
5. Inert electrodes like platinum (Pt) are used when there is no solid metal to act as an electrode.
