Concentration of CS Rule of Thumb If my math is right, here is a rule of thumb that you can use for approximating the maximum concentration of CS when you make it...
"The maximum concentration for 1 cup of CS made at 1 milliamp for one hour would be approximately 17ppm." Reasoning: Each Coulomb of electricity will deposit .001118 grams of silver into solution. A Coulomb is 1 ampersecond. For example, 1 cup of water is 227 grams. Run it for 1 hour at 1 milliamp. Find the number of seconds: 1 hour = 60 seconds/minute x 60 minutes = 3600 seconds Find the number of Coulombs: .001 amps x 3600 seconds = 3.6 ampseconds = 3.6 Coulombs Find the amount of silver released: 3.6 columns x .001118 grams/coulomb = .00402 grams of silver released into solution Find the ratio or water to silver: 227 grams of water / .00402 grams of silver = 56467 / 1 Find the parts per million: 1,000,000 / 56467 = 17ppm So, the rule of thumb would be: "The maximum concentration for 1 cup of CS made at 1 milliamp for one hour would be 17ppm." This assumes that the current is at 1 ma from start to finish of the hour. (If it took 1 hour for the current to go from zero to 1 ma then the concentration would be approximately half (8.5ppm) for that hour, assuming that the current increase is reasonably linear at this stage.) These values are approximate and indicate the *maximum* concentration you can get. Your effective CS concentration will be somewhat less. Using this value you can quickly get a rough estimate of your (max) CS concentration by figuring out the number of cups in your jar, the run time in hours, and the current in milliamps.

Good Morning dear C S Fellows! Concerning our home-factory of C S: We are working on a stock of C S, in order not to have to say "no" to anybody in need. We've been on the time-span during which C S can be stocked, I remember it is rather long, if not cooled in the fridge, and that is okay. Question: How MUCH can one make in one shot, in other words: What is the greatest amount of water one can safely process, for one half hour's brew? (We use rods of 12 cm in length -that would be about 5 inches if I'm not mistaken- and 2 millimeter in diameter, with 30 volts/400 milliamps. Thanks again!
