Nitric acid - Wikipedia
Nitric acid is an inorganic compound with the formula H N O 3. It is a highly corrosive mineral acid. [6] The compound is colorless, but samples tend to acquire a yellow cast over time due to decomposition into oxides of nitrogen. Most commercially available nitric acid has a concentration of 68% in water.
Acid azotic - Wikipedia
Acidul azotic, cunoscut și sub numele de acid nitric, este unul dintre cei mai tari acizi anorganici (minerali). Formula chimică este HNO 3. El este totodată, în stare pură sau concentrat, și un agent oxidant foarte puternic. În stare pură, acidul azotic este un lichid incolor, cu miros înțepător, ușor solubil în apă.
Nitric Acid - an overview | ScienceDirect Topics
Nitric acid – also known as aqua fortis or azotic acid – is an inorganic acid of major industrial importance. Due to its properties as a very strong acid, a powerful nitration and oxidising agent, nitric acid is crucial in the production of many chemicals, e.g., pharmaceuticals, dyes, synthetic fibres, insecticides, and fungicides [91] .
