Liquid junction potential in Weston cadmium cell

Click For Summary
SUMMARY

Liquid junction potential is a critical phenomenon observed when two solutions of differing concentrations come into contact, leading to a diffusion gradient. In the context of the Weston cadmium cell, which utilizes a HgCl2 and Cd configuration, the liquid junction potential plays a significant role in the electrochemical behavior of the cell. The diffusion rate is influenced by the mobility of ions, which is essential for understanding the cell's functionality and efficiency.

Liquid junction potential occurs when 2 solutions of different concentrations are in contact with each other.
The more concentrated one would have tendency to diffuse faster comparitively than less concentrated.
The rate of diffision depends on the mobility of ions.

Weston cadmium cell is hgcl2 Cd cell. In this case how?
