Aqua Regia (Latin for “royal water”) is an acidic, corrosive, and oxidative mixture of three parts concentrated hydrochloric acid (HCl) and one part concentrated nitric acid (HNO3). It is called aqua regia because it is one of the few acid mixtures that can dissolve the “noble” metals: gold (Au), platinum (Pt), and palladium (Pd). 👉👉👉 www.youtube.com/@MakeGold/videos #aquaregia | Archimedes Channel

By Alchemists GOLD Aqua regia is a mixture of nitric acid and hydrochloric acid, in ratio of 1:3 Aqua regia is a fuming liquid. Freshly prepared aqua regia is colorless, but it turns yellow, orange or red within seconds. 👉👉❤️😘 I hope you like our video. Please like and share the video to your friends.

The usual ratio of acids is 3 parts hydrochloric acid to 1 part nitric acid. When mixing the acids, it is important to add the nitric acid to the hydrochloric acid and not the other way around. Aqua regia is used to dissolve gold, platinum, and palladium. The ac

Making Poorman Aqua Regia and Dissolving Metals in It.

While soaking CPU pins in nitric acid is a crucial **preliminary step** to dissolve the non-gold metals, **nitric acid alone will not dissolve pure gold** or cause it to "fall off" as a usable product. The subsequent step—dissolving the gold itself—requires the use of the far more dangerous chemical combination, **Aqua Regia**, a process reserved for professional or highly experienced refiners. | Archimedes Channel
