Hi Marshall, Yes, I have one reference that also states silver carbonate is yellow and includes pictures. Others state it is tan or brown, so it may depend on the purity. I think the brown residue I saw once was contamination from letting the rods rest on the table. I got very ill for several days after drinking the cs. I then made a simple holder from a plastic cap to keep the rods from touching anything while transferring liquid to and from the cs generator. The brown spots disappeared and were replaced by black spots under the rods. I saw a brown spot once again after moving the rods to a bigger cap to double the wetted area. I discarded the cs and made another batch. Then I then discovered the benefits of running at low current density. This eliminates the production of silver oxide, Ag2O, that formed the black spots and coated the inside of the glass. It also increases the maximum concentration of silver ions that can be produced before the solution starts turning yellow or black. I estimate the maximum ppm I obtained at 1.4 mA/sq.in. was on the order of 10 ppm. Recent runs indicate the cs made at 87uA/sq.in. reaches a calculated 28 ppm before it starts showing a pale yellow tint. I can post the data and calculations if you like, but omit them here to save space. Adding 1 teaspoon of ordinary 3.5% H2O2 per litre turns the solution completely clear and increases the strength of the dispersion in the salt test. Because of this, I believe adding H2O2 to a solution containing silver oxide particles forms a catalytic reaction that releases silver ions and oxygen: Ag2O + H2O2 --> Ag(+) + O2(g) + H2O2 According to my references, 1 teaspoon is 5 ml. So this is 5*.035 = 0.175ml H2O2, or 0.175 ppm H2O2. It is barely noticeable when tasting the cs. Probably half as much would have the same effect and be even less noticeable.
