Hi there,
I'm new, and have a conceptual question regarding the LVDC 'constant
current' method of CS synthesis.
When running a batch at a constant current, the voltage steadily
decreases and the electrical conductivity of the solution increases (at
a slower and slower rate) over time.
Once the rate of change of the electrical conductivity remains
relatively consistent, I understand that the Ag ion concentration (in
solution) has reached a saturation point.
What happens next ... ? Does continued electrolysis begin oxidizing
ions out of solution, some depositing on the electrodes and presumably
some neutral particles remain in a colloidal state?
Is the process finished once this saturation point is reached? Or does
continued electrolysis convert a percentage of the ionic Ag solution
into colloidal Ag particles?
Thanks in advance for any clarification,
Shane
