Hello Everyone!
I would like to know which physics modules I need to apply to track the concentration of silver ions through a pipe section. The silver ions dissolve in water by ionization (applying current to a silver electrode). I would like to make the current or the voltage a parameter for the concentration of silver ions. I was planning to use the "Particle Tracing for Fluid Flow" or the "Transport of Diluted Species", but which these modules I can not include the applied current to the electrode as a parameter.

Yes you can. Use flux boundary condition on the electrode:
Flux = I/F
I = current (A) F = Faraday constant = 96500 As/mol
Hence, Flux = ( ) mol/s.
