What type of amine is tetramethylammonium?
Tetramethylammonium (TMA) or (Me4N+) is the simplest quaternary ammonium cation, consisting of four methyl groups attached to a central nitrogen atom, and is isoelectronic with neopentane. It is positively charged and can only be isolated in association with a counter-ion.
Is aqueous ammonia ammonium hydroxide?

What is the pH of ammonia?
11-13
Ammonia: pH 11-13.
Is ammonium acidic or basic?
Ammonia solution is said to be a weak base. This is because the ammonia’s nitrogen atom has an electron pair that easily accepts a proton. When ammonia is in water it can readily gain hydrogen ions to form hydroxide and ammonium ions.
