 Cadet's fuming liquid

Cadet's fuming liquid, also known as "Cadet's fuming liquid," is an aqueous solution of nitrogen dioxide (NO2) in nitric acid (HNO3). This solution is characterized by its intense yellow-brown color due to the presence of nitrogen dioxide gas, which can dissolve in the acid to form a mixture. Cadet's fuming liquid is used in various chemical processes, including the production of explosives and in the context of certain types of chemical synthesis.
