Junction Potential Calculator
Calculate the liquid junction potential between two solutions
Cation
Anion
About Junction Potential
The liquid junction potential arises when two solutions of different composition are in contact. It occurs because ions diffuse at different rates.
Minimizing Ej: Use a salt bridge with KCl or KNO₃ where cation and anion have similar mobilities (t+ ≈ t-).
