Abstract

CETTE ELECTRODE PERMET DE DETERMINER LA CONCENTRATION TOTALE EN IONS LIBRES DES SOLUTIONS. ELLE EST CARACTERISEE EN CE QUE LA TENSION ELECTRIQUE G, OBTENUE PAR LA MISE EN CONTACT ELECTROCHIMIQUE DE CETTE ELECTRODE AVEC UNE SOLUTION TEST, VARIE LINEAIREMENT AVEC LE LOGARITHME DE LA SOMME DES PRODUITS CONCENTRATION-MOBILITE DE TOUS LES IONS LIBRES PRESENTS DANS CETTE SOLUTION SUIVANT UNE RELATION DE TYPE NERNST OU LA DISTANCE A L'ORIGINE ET LA PENTE SONT CONSTANTES POUR UNE ELECTRODE-SOMME DONNEE ET POUR UNE TEMPERATURE ET UNE PRESSION DONNEES, L'ELECTRODE-SOMME AYANT LA PROPRIETE D'ETRE TOTALEMENT NON SELECTIVE, NE DISCERNANT PAS ENTRE LES DIVERS IONS LIBRES DE LA SOLUTION AVEC LAQUELLE ELLE EST EN CONTACT.
