I'll be elaborating here in the near future as well.
your gold along with the base metals due to the excessive amount of chlorine produced. If you think about the etching reaction you will realize that the active ingredient is the copper II chloride, not the peroxide or the muratic acid. With this in mind the water is necessary to allow the exchange of the copper metal ions in liquid form.
Hydrochloric acid and hydrogen peroxide (Main article : Dissolving gold with hydrochloric acid and hydrogen peroxide ) Another alternative to aqua regia is to use hydrochloric acid and hydrogen peroxide, the hydrogen peroxide is a strong enough oxidizer to have the power to dissolve gold but not as fast as aqua regia.

Jul 21, 2008· I'm curious as to why you guys use Acid Peroxide instead of Aqua Regia in the first step (most of you). It seems to me that Aqua Regia skips a step in the process by dissolving the gold in step #1. Whereas with Acid Peroxide you have to strip the foils, then dissolve them with Acid/Chlorine in step #2. Is it a safety thing? Cost? Efficiency??
peroxide muriatic acid gold refining make auritic salt. It makes gluconic acid and hydrogen peroxide, which are, processing, paper manufacturing, electronics, oil refining, mining and to treat, The Merck Manual is the 'gold standard' of treatment guidelines for physicians.
