• fumes
  • While the pure acid tends to give off white fumes when exposed to air, acid with dissolved nitrogen dioxide gives off reddish-brown vapors, leading to the common name "red fuming acid" or "fuming nitric acid" - the most concentrated form of nitric acid at Standard Temperature and Pressure (STP).

  • NaOH
  • It took 39.22 ml of 0.2334 M NaOH to titrate 25.00 ml of the acid. (jiskha.com)
  • In the first step, ammonia is converted to sodium amide: 2 Na + 2 NH3 → 2 NaNH2 + H2 The sodium amide is subsequently combined with nitrous oxide: 2 NaNH2 + N2O → NaN3 + NaOH + NH3 These reactions are the basis of the industrial route, which produced about 250 tons/y in 2004, with production increasing owing to the popularization of airbags.

  • nitrates
  • The name nitrogène was suggested by French chemist Jean-Antoine-Claude Chaptal in 1790, when it was found that nitrogen was present in nitric acid and nitrates. (wikipedia.org)

  • glacial
  • It condenses with acids or acid chlorides, in the presence of dehydrating agents, to oxyketones, e.g., with zinc chloride and glacial acetic acid at 145 °C it yields resacetophenone (HO)2C6H3~CO.CH3. (wikipedia.org)

  • The color of ammonium chloride or ammonium hydroxide solution will vary depending upon the concentration of azo violet used. (wikipedia.org)
  • Phenolic
  • Phenolic glycolipids (( 8 )) and cyclopropanated mycolic acids (( 9 )) protect the cell wall, while catalase, alkylhydroperoxide reductase (( 10 )), and superoxide dismutase (( 11 ), ( 12 )) guard the cytosol. (rupress.org)
  • volatile
  • It is not as volatile nor as corrosive as the anhydrous acid and has the approximate concentration of 21.4 molar. (wikipedia.org)
