In aqueous solution, ammonia deprotonates a small fraction of the water to give ammonium and hydroxide according to the following equilibrium: . NH 3 + H 2 O ⇌ NH + 4 + OH −.. In a 1 M ammonia solution, about 0.42% of the ammonia is converted to ammonium, equivalent to pH = 11.63 because [NH +
UN Number Class Proper Shipping Name UN 2601: 2: Cyclobutane: UN 2602: 2: Dichlorodifluoromethane and difluoroethane azeotropic mixture or Refrigerant gas R 500 with approximately 74 percent dichlorodifluoromethane
Ammonium hydroxide is commonly used but it doesn't seem to be an accurate name. There is only a small fraction of ammonium ions and hydroxide ions in NH3(aq). I think ammonia solution is more appropriate as the title. In google, "ammonium hydroxide" and "ammonia solution" have similar popularity. Both of them have more than 600,000 links.
After the invention of the Haber and other new ammonia-producing processes in the 1910s and 1920s its price dropped, and there was less need in reclaiming it. So in the modified Solvay process developed by Chinese chemist Hou Debang in 1930s, the first few steps are the same as the Solvay process, but the CaCl 2 is supplanted by ammonium ...

TMAH is a stable compound, with a half-life longer than 61 h in 6 M NaOH at 160 °C. [5] TMAH undergoes simple acid-base reactions to produce tetramethylammonium (TMA) salts whose anion is derived from the acid used. Illustrative is the preparation of tetramethylammonium fluoride: [6] NMe 4 + OH − + HF → NMe 4 + F − + H 2 O
