Red fuming nitric acid - Wikipedia
Red fuming nitric acid (RFNA) is a storable oxidizer used as a rocket propellant. It consists of 84% nitric acid (H N O 3), 13% dinitrogen tetroxide (N 2 O 4) and 1–2% water. [1] The color of red fuming nitric acid is due to the dinitrogen tetroxide, which breaks down partially to form nitrogen dioxide. The nitrogen dioxide dissolves until ...
Nitric acid - Wikipedia
When the solution contains more than 86% HNO 3, it is referred to as fuming nitric acid. Depending on the amount of nitrogen dioxide present, fuming nitric acid is further characterized as red fuming nitric acid at concentrations above 86%, or …

2013年4月26日 · Concentrated nitric acid containing dissolved nitrogen dioxide is termed fuming nitric acid, which evolves suffocating, poisonous fumes of nitrogen dioxide and nitrogen tetroxide (O'Neil et al. 2006).
NITRIC ACID, RED FUMING | CAMEO Chemicals | NOAA
NITRIC ACID, RED FUMING is a powerful oxidizing agent and nitrating agent. Accelerates the burning of combustible material and may cause charring and then ignition of combustible materials.
Nitric acid at concentrations greater than 86% is considered to be fuming nitric acid, which is significantly more hazardous. Laboratories using fuming nitric acid should develop an SOP specifically

Concentrated Nitric Acid vs. Fuming Nitric Acid - This vs. That
Fuming nitric acid, also known as "white fuming nitric acid" or "WFNA," is a more concentrated and highly reactive form of nitric acid. It contains a higher concentration of nitrogen dioxide (NO 2 ) gas, which gives it a characteristic yellowish or reddish-brown color and a fuming appearance.
