NH3 can accept a proton ( hydrogen ion ) to become NH4(-), ammonium. This is the definition of a base; accepting protons. NH3 is a weak base.

What is the difference between ammonia and anhydrous ammonia and ammonium hydroxide?

Anhydrous ammonia is really just ammonia in fact. "Anhydrous" means without water, and anhydrous ammonia is just pure ammonia without water.It is to distinguish it from ammonia in water solutions because when added to water ammonia forms ammonium hydroxide:NH3 + H2O ---> NH4+ + OH-Ammonium hydroxide is frequently referred to as ammonia because you make it by adding ammonia to water, but it isn't really ammonia. It is much more commonly though because it is easier to handle (ammonia is a gas).See the Web Links for more information about ammonia.


What is Ammonium Hydroxide?

Ammonium hydroxide (NH4OH) is a common, though not entirely correct name for a solution of ammonia dissolved in water.when dissolved in water ammonia reacts to a small degree with water to produce ammonium hydroxide (NH3 + H2O --> NH4OH). But this only forms in a small amount and most of the ammonia remains unreacted. This substance cannot be isolated as any attempt to separate it out will result in it reverting back to ammonia and water.its the state that daisy go into after an animal has urinated on it


Why ammonium hydroxide cannot be primary standard?

Because it is a instable solution of gaseous ammonia (NH3) in water. (cit.) Ammonium hydroxide (NH4OH) is a common, though not entirely correct name for a solution of ammonia dissolved in water. When dissolved in water ammonia reacts to a small degree with water to produce ammonium hydroxide solution (NH3 + H2O --> NH4+ + OH-). But this only forms in a small amount ammonium (NH4+) and most of the ammonia remains unreacted as NH3. 'Ammonium hydroxide' substance cannot be isolated at all, as any attempt to separate it out will result in it reverting back to ammonia and water. (from wiki-answers)


Is ammonium an acid or base?

Unlike it's weak base counterpart, ammonia (NH3), ammonium (NH4) is an acid.


Why does ammonia hydroxide not react with calcium?

I'm not the best at chemistry just thought i would try to help. anyways I'm pretty sure its to do with how ammonia hydroxide cant break down the calcium for it to react. Full marks for trying. However, permit me to supply something a bit closer to the mark. ===================== I do not think the questioner has that question right. Ammonium hydroxide would react strongly with calcium, which is a reactive metal that bubbles hydrogen in contact with water. If you put some calcium metal in with ammonium hydroxide, it would immediately give off bubbles of hydrogen, and produce calcium hydroxide, releasing ammonia gas. I suppose that the question you really want to ask has something to do with why a dilute calcium hydroxide does not release ammonia from ammonium compounds. If that is what you want to know, the answer might be something like that calcium hydroxide is a weak base, too weak to displace the ammonium and produce ammonium hydroxide. I have my doubts though; that does not make much sense. I think you had better put more preparation into your homework. You cannot get anywhere in chemistry without taking trouble to understand it.

Chemical formula of ammonium hydroxide?

The Chemical formuls for ammonium hydroxide is = NH4OHAdded:I'm very sorry to inform you that ammonium hydroxide, much better known as ammonia, does NOT exist. Citation in wikipedia:Ammonium hydroxide, also known as ammonia water, ammonical liquor, ammonia liquor, aqua ammonia, or aqueous ammonia, is a solution of ammonia in water. It can be denoted by the symbols NH3(aq). Although its name suggests a salt with composition [NH4+][OH−], it is not actually possible to isolate samples of NH4OH - it exists only in dilute aqueous solutions.NH4+ is not an alkali metal, though it forms halogenides, nitrates and other salts like K+ and Na+.In a 1M ammonia solution, about 0.42% of the ammonia is converted to ammonium, NH4+, equivalent to a pH of 11.63.NH3 + H2O NH4+ + OH−.The base ionization constant isKb = [NH4+][OH-]/[NH3] = 1.8×10−5The name is ammonium hydroxide, and is an ionic compound composed of two polyatomic ions, NH4+, the ammonium ion, and OH-, the hydroxide ion. The formula for ammonium hydroxide is NH4OH.


Are Bacteria a species?

Most bacteria are classified in the Kingdom of Eubacteria. Though bacteria sometimes is not classified as a living organism, some do contain DNA and RNA.
