Classification of Junction Potentials 3 Categories of Junction Potentials Type 1: 2 solutions of same electrolyte with different concentrations in contact Type 2: 2 solutions of same concentrations of electrolytes in contact which share a common univalent(z-1)ion Type 3: 2 different solutions containing different electrolytes and/or different concentrations in contactClassification of Junction Potentials 3 Categories of Junction Potentials: Type 1: 2 solutions of same electrolyte with different concentrations in contact Type 2: 2 solutions of same concentrations of electrolytes in contact which share a common univalent (z=1) ion Type 3: 2 different solutions containing different electrolytes and/or different concentrations in contact
