Nitrohydrochloric Acid, also known as aqua regia, is a highly corrosive and effective chemical mixture used to dissolve metals. Its spelling is a reflection of the chemical compounds it contains, nitrogen dioxide (NO2) and hydrochloric acid (HCl). The IPA phonetic transcription for Nitrohydrochloric Acid is /naɪtroʊˌhaɪdrəˈklɔrɪk æsɪd/, which breaks down each syllable and sound in the word. This complex spelling reminds us of the complex chemistry behind its power and effectiveness.
Nitrohydrochloric Acid, also known as aqua regia, is a highly corrosive mixture of concentrated nitric acid (HNO3) and concentrated hydrochloric acid (HCl). The term 'nitro' refers to the nitric acid component, while 'hydrochloric' refers to the hydrochloric acid component of this mixture. The resulting acid is called 'aqua regia,' meaning 'royal water' in Latin, due to its ability to dissolve gold and platinum, which were historically considered as royal metals.
Nitrohydrochloric Acid is a yellow-orange liquid that emits a pungent and suffocating odor. It is highly reactive and capable of dissolving a wide range of metals and metal oxides, making it a valuable tool in various laboratory applications, particularly in the field of chemical analysis.
The strong oxidizing nature of the nitric acid component and the strong reducing capabilities of the hydrochloric acid component combine to create a powerful and versatile acid. When used together, they can dissolve noble metals like gold, platinum, and palladium, as well as some other less reactive metals, such as copper and iron.
Due to its extremely corrosive and reactive nature, handling Nitrohydrochloric Acid requires significant caution and expertise. It should be used in well-ventilated areas, preferably under a fume hood, and proper personal protective equipment, such as gloves, goggles, and a lab coat, should be worn while working with it.
The unique properties of Nitrohydrochloric Acid, including its ability to dissolve noble metals, make it an indispensable tool in various fields of science, especially in analytical chemistry, where it is used to prepare samples for elemental analysis.
Nitromuriatic acid, aqua regia, acidum nitrohydrochloricum.

The word "Nitrohydrochloric acid" is composed of two main components: "nitro-" and "hydrochloric acid".
The term "nitro-" is derived from the Latin word "nitrum", which means "native soda" or "potassium nitrate". Over time, "nitro-" has come to refer to chemical compounds or groups that contain the nitro functional group (NO2-).
The term "hydrochloric acid" originates from the combination of "hydro-" and "chloric acid". "Hydro-" derives from the Greek word "hudōr", meaning "water", and indicates the presence of water in the compound. "Chloric acid" refers to an acid derived from chlorine and originates from the Latin word "chlorum", meaning "pale green" or "yellow-green".
