Ammonia solution, also known as ammonia water, ammonium hydroxide, ammoniacal liquor, ammonia liquor, aqua ammonia, aqueous ammonia, or (inaccurately) ammonia, is a solution of ammonia in water. It can be denoted by the symbols NH 3 (aq). Although the name ammonium hydroxide suggests a salt with the composition [NH + 4][OH −

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.
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

Using its low solubility in water, it can also be precipitated from an iodate solution with an ammonium salt. 2 KIO 3 + (NH 4) 2 SO 4 → 2 NH 4 IO 3 + K 2 SO 4. Unlike other iodates, ammonium iodate can't be prepared by dissolving iodine in an ammonium hydroxide solution, instead the highly explosive nitrogen triiodide is formed. 3 I 2 + 5 NH ...
