	Process for manufacture of ultra-high purity ammonium hydroxide - Patent 5746993
		Aqueous ammonium hydroxide solutions for use in semiconductor chip fabrication cleaning operations are usually manufactured by a known batch process wherein a large tank (e.g., 3000 gallons) is first filled with pure water which is then pumped to an injector/sparger wherein it is mixed and combined with ammonia gas.
		Ammonium hydroxide forms as ammonia gas is injected into a perforated PFA sparge tube 13 immersed in water from line 11.
		Ammonium hydroxide solution produced in the first reactor 8 flows to the first heat exchanger 15 which cools the temperature of the solution from temperatures as high as 90.degree.

	Ammonium hydroxide
		Ammonium hydroxide (NH OH) is the name given to an aqueous solution of ammonia.
		Since ammonia ionizes to a small extent, ammonium and hydroxide ions will be present in an aqueous solution of ammonia.
		Ammonium hydroxide was an attempt by chemists to apply Arrhenius theory which did not seem to work earlier as Ammonia does not have any hydroxide ions (which Arhennius said was required for a substance to have alkaline properties).

	Megalomania's Method of Making Ammonium Nitrate
		Ammonium hydroxide, the main ingredient, can be obtained in dilute solution as a laundry substance or as a window cleaner, it is ammonia.
		The ammonium nitrate is formed by a simple double displacement reaction when the ammonium ion, NH +, replaces the H+ ion from the nitric acid and bonds to the remaining nitrate ion, NO, then the H+ ion forms water from the hydroxide ion, OH-, left by the ammonium ion.
		Slowly add ammonium hydroxide from a beaker to the Erlenmeyer flask while stirring by swirling the flask occasionally until the mixture is alkaline to litmus paper.

		[4]When acidified with HNO3, the Al and Mg hydroxides are dissolved as the H of the acid reacts with the OH of the precipitates and the metal ions are in solution as nitrates.
		This is a salt of a weak base and a strong acid [pure ammonium nitrate in solution has a pH of about 5.4] So the solution is now strongly buffered, look at the pHs of the hydroxides in [2] above.
