Aqua regia is known as royal water because it has the ability to dissolve various metals, which are extremely hard to dissolve. It can dissolve gold, platinum, and other noble metals. Noble metals can be defined as those metals that show high resilience to chemical attacks.
Aqua regia, as we know, consists of nitric acid, i.e., HNO3 which acts as a strong oxidizing agent. This nitric acid converts the gold or platinum metal to their corresponding ions by oxidizing them.

Does aqua regia dissolve gold
Aqua regia dissolves the gold, although the acidic ingredient does so on its own. Nitric acid is a strong oxidizing agent and actually dissolves almost the latent amount of gold, forming silver ions (Au 3+ ).
What is aqua regia in chemistry
Definition of aqua regia. Aqua regia is a mixture of hydrochloric acid (HCl) and nitric acid (HNO3) in a ratio of 3:1 or 4:1. It is a red-orange or yellowish-orange fuming liquid. The word is an expression interpreted in Latin as “aqua regia”. The name reflects the ability of aqua regia to dissolve the precious metals gold, platinum and palladium.
What happens when platinum reacts with aqua regia
The product of the reaction of aqua regia with metallic platinum is nitrosoplatinum chloride, which is formed in a healthy state. In addition, this solid compound reacts with 2 molar hydrochloric acid urate crystals to form nitrosylchloroplatinic acid in addition to chloride.
What happens when gold reacts with aqua regia
Aqua regia is good for dissolving gold itself (as well as dissolving silver and just copper components) and for this purpose is used to test supercarat gold alloys. Aqua regia melts gold in two separation reactions.
What is aqua regia How does it dissolve gold write its equation
Since aqua regia is another mixture of two strong acids, it does not have its own chemical formula. However, it can be represented as HNO3 + 3 HCl, which basically suggests that it is a mixture of nitric acid (HNO-3) and hydrochloric acid (HCl).
What is aqua regia name two metals which do not dissolve in other reagents but dissolve in aqua regia
Aqua regia, often referred to as aqua regia, is a combination of hydrochloric and nitric acids in a 3:1 molar ratio. It is so called because the precious metals platinum and gold can dissolve. Thus, various insoluble special metals, the last common reagent but soluble in aqua regia, may be gold and therefore platinum.

What is aqua regia How does it dissolves gold and platinum
As people all over the world know, aqua regia is made up of nitric acid, which is HNO3, which acts as a strong oxidizing agent. This nitric acid completely converts metallic gold or platinum into the corresponding ions, oxidizing them.
When gold dissolves in aqua regia products formed are
When gold is dissolved in aqua regia, chloroauric acid is formed. So really correct the answer “Option B”.
