Both. Actually, enough CO2 is absorbed into the water just being exposed to the air. To get more CO2 into the water, bubble air through the water. The water is nowhere near saturated with CO2, only a small amount of CO2 adds plenty of anions. To prevent CO2 from getting in, draw the DI water into an argon filled vessel, and maintain argon over the water during processing. You will then notice that the silver saturation point is lower than if the DI water was exposed to air. Keep in mind, I am referring to DI water of 0.05 uS/cm at point of origin. This level of purity is very difficult to maintain. Exposure to air for a few seconds adds CO2 which contaminates the water. The practical value of this information is that it is possible to produce a DC generated cs of higher ppm concentration without turning yellow by simple bubbling air through the water as the process is working. By adding air (CO2) carbonate anions are available to counter the silver cations. So the solution can hold more silver anions without becoming saturated. As the solution cools and ages, agglomeration is reduced because the solution was not supersaturated. CO2 gas should be added, only air. Too much CO2 will form carbonic acid and lower the pH. frank key >>
Frank: In your statements above, please point out which ones were made referring to actual AA measurements of silver concentration, and which ones were based on theoretical calculations.
