Cell Notation
Abbreviated symbolism is commonly used to represent a galvanic cell by providing essential information on its composition and structure.

Guidelines
Guidelines
- Cell notations are written following a few guidelines:
- The relevant components of each half-cell are represented by their chemical formulas or element symbols.
- All interfaces between component phases are represented by vertical parallel lines.
- If two or more components are present in the same phase, their formulas are separated by commas.
- The schematic begins with the anode and proceeds left-to-right identifying phases and interfaces encountered within the cell, ending with the cathode.

Example
Example
- Taking the example of the galvanic cell based on the reaction between copper and silver(I) ions:
- The cell consists of a solid copper anode (left) immersed in an aqueous solution of copper(II) nitrate.
- The cell is connected via a salt bridge to an aqueous silver(I) nitrate solution, immersed in which is a solid silver cathode (right).
- Converting this statement to symbolism following the above guidelines results in the cell schematic:
- Cu(s)│1M Cu(NO3)2(aq)║1M AgNO3(aq)│Ag(s)
