Gold indicator solution.

[Elektrikis]

Hi!

Some tests positive some negative.

One liter solution make by 18 grams mixed powders. Worth 0.57 dollar but only dissolve 0.6 grams of gold.
Zinc precipitation is best choice. Ph 6 and 4 grams of zinc per 1 gram Au.
Electrolysis works.

I like it as an electroplating solution.

Please we are interested in purchasing your reagent but at what PH Levels does it work? Because the vessels we use are limited to some pH levels

FYI, unfortunately Elektrikis has not been here in a long time (last seen November 01, 2021). So it is unlikely your question will ever be answered.
