Definition 1
On appelle constante de cellule k le rapport de la conductance G et de la conductivité σ de la solution.
Definition 2
On note λ la conductivité molaire ionique de l’ion oxonium H3O+ et λ’ la conductivité molaire ionique de l’ion éthanoate CH3CO2–.
(1) HCl(g) + H2O(l) = H3O+(aq) + Cl–(aq)
Page 1
(2) H2SO4(l) + 2 H2O(l) = 2 H3O+(aq) + SO42–(aq)
