The composition of aqua regia is (three parts concentrated hydrochloric acid and one part concentrated nitric acid), while the composition of anti-aqua regia is (three parts concentrated nitric acid and one part concentrated hydrochloric acid).

The composition of aqua regia is (concentrated nitric acid and concentrated hydrochloric acid in a volume ratio of 1:3), while the composition of reverse aqua regia is (concentrated nitric acid and concentrated hydrochloric acid in a volume ratio of 3:1).

Reverse aqua regia: also known as Lefort’s aqua regia, it is a mixture of three parts nitric acid and one part hydrochloric acid. It can be used to dissolve sulfur oxides and pyrite, and it has a stronger oxidizing power than regular aqua regia; it is capable of dissolving metals such as Ag, Hg, Mo, as well as the sulfides of Fe, Mn, and Ge. Because the prepared mixed acid is red in color, it is also known as red acid.

The composition of aqua regia is (concentrated nitric acid and concentrated hydrochloric acid in a volume ratio of one to three), while the composition of reverse aqua regia is (concentrated nitric acid and concentrated hydrochloric acid in a volume ratio of three to one).

Aqua regia is a mixed acid prepared by combining hydrochloric acid and nitric acid in a volume ratio of 3:1; it is commonly referred to as “hydrochloric acid, nitric acid, and water in a 3:1 ratio.” The reverse of this mixture is called inverse aqua regia. Since the resulting mixed acid is red in color, it is also known as red acid; it can also be formed by allowing ordinary aqua regia to stand for some time. It has a stronger oxidizing power than aqua regia, and can dissolve metals such as Ag, Hg, Mo, etc., as well as the sulfides of Fe, Mn, and Ge.

Aqua regia: A mixture composed of concentrated hydrochloric acid (HCl) and concentrated nitric acid (HNO3), with a volume ratio of 3:1. Reverse aqua regia: Has the same composition as aqua regia, but with a volume ratio of HCl to HNO3 of 1:3
