The anodic growth of lead chloride and lead sulphate on a saturated lead amalgam electrode

The electrocrystallization of lead chloride and lead sulphate on a lead amalgam electrode has been studied. The instant at which the nuclei start to grow shows up most clearly in the light scattering signal, while in potential sweep and potential step experiments that instant is less identifiable or almost undetectable in the current transient. The light scattering patterns also show the changes in surface roughness during the process.
