Hi Ya'all, Just thought that I would take a few minutes to add some information to the subject.
The Faraday law is for a high efficiency plating solution where the resistance on the solution is a few ohms or very high conductance. The liquid for silver plating is basiclly sodium cynanide. (very poisionous).As I recall 93,000 coulombs will deposite 1.02 grams of silver. The coulomb is a unit of power. For those using a constant voltage source that draws just a few milliamperes the voltage will remain fixed, so if one plots cell current vs time and then integrates the area under the curve and multiples by the voltage then one has the power used in the cell. Now convert that to coulmbs and work out the answer. For a constant current generator one must plot both voltage and current to get the power involved in the process as they both change as the process runs until the constant current level is reached. Then how long do you let it run at a fixed current? Unfortunately, nothing is easy anymore! If you use a very thin cathode and weight it to 2 or 3 decimals before you start and again after you finish then you will know theamount of silver that plated out, so subtract that from you calculation, and walla you have an answer. I don't knowif it is right or not but then maybe Marshall will enlighten us. "Ole Bob" -- The silver-list is a moderated forum for discussion of colloidal silver.
