It is impossible to make 400 ppm CS that looks like something you'd let a mangy stray dog drink....but you can make "sludge" that strong, not know you are and believe it's worth over using.

Does anyone know a correct % solution for making silver acetate. For citric acid (CS) a 5 % solution is being used. I can control the mA and use Faraday calc to determine the ppm. I am in Brazil right now and Distilled water is hard to come by and would like to make some high ppm CS in case of emergency. I would be able to dilute it down using the mineral water here. The city water is pretty bad and we have had little rain here for some unknown reason. The streets are dusty and I live in a tropical region.
If I can I would like to make 400 ppm CS and dilute it 10 to1 or 20 to 1.
