You can figure out an outside limit (ideal case assuming 100% efficiency) for
silver production from basic chemistry principles.
A few terms:
MOLE: a very large standard number of atoms or molecules, such that the weight
of one mole of a substance is equal to the atomic or molecular weight in grams.
The atomic weight of Silver is approximately 107.
COULOMB: the standard unit of electrical charge. One mole of electrons has a
charge of approximately 96,500 coulombs.
AMPERE: the standard unit of electrical current, or rate of moving charge. One
coulomb per second is defined as one ampere, or Amp. 1 Amp = 1000 Milliamps.
If you are running a constant current process, you can calculate this limit
simply:
number of grams of silver = multiply current in amps times time of the
process in seconds Divide by 96,500 to get moles of electrons. Since silver
is singly ionized, then multiply by 107 to get the number of grams of silver.
Compute ppm weight by assuming that 1 liter of water = 1000 grams. 1 ppm = 1
milligram per liter.
Example: current = 1 milliamp time = 5 minutes amount of water = 1/2 liter
by the above math then:
total coulombs = 0.3
total moles = .00000310 (3.10 micromoles)
total grams of silver = .00032 (0.32 milligrams)
total grams of silver per liter .00064 (0.64 milligrams)
parts per million by weight 0.64
If you are running a constant Voltage process, it is more complicated. The
silver production is a function of current, not voltage. The voltage produces
current according to ohms law (voltage divided by the resistance of the
circuit). The problem is the resistance of the distilled water is constantly
changing, since the CS you produce lowers the resistance. Technically you
would have to integrate the current over time, in practice you can estimate in
blocks with measured resistance or current.
Also remember this is a THEORETICAL UPPER LIMIT for silver production, not a
prediction of actual production values.
