Description
Physicochemical equality (symbol =) indicates in an equation not only numerical equivalence (symbol β‘), but an identity of the full meaning.
Abbreviation: =

Example
- Iconic symbols indicate equality beyond equivalence, for instance in equations for the protonmotive force pmF (Blue Book Eq. 8.1 and 8.2)
- Conventional symbols:
The protonmotive force pmF Format Definition Units charge format: Ξp β‘ βπH+ β (π§H+ β πΉ)β1 + βπΉp+ [JβC-1 = V] amount format: ΞπΜ H+ β‘ βπH+ + βπΉp+ β (π§H+ β πΉ) [Jβmol-1 = Jol]
- Iconic symbols: ΞmFH+ = ΞdFH+ + ΞelFp+
