Question on Aqueous Ammonia

Question

Is aqueous Ammonia NH3(aq) or is it NH4OH?

I am confuss because if i don't get this right, i can't form the correct equation

Answer 1

NH4OH is ammonium hydroxide.

Answer 2

Aqueous ammonia is really NH3, a weak base which reacts to a very small extent (roughly 1 part per thousand) with water to give NH4plus and OH-, although it reacts almost quantitatively with acids  that are stronger acids than water.

It is very misleading, but reagent bottles are often labelled "NH4OH". The truth is that you cannot write NH4OH as a single species without breaking the rules of valency.

Answer 3

aqueous NH3 means ammonia in presence of water...  that doesnt mean NH4OH.... for some reaction we take it for the formation of NH4+ so that it can react with the other reactant...... OH- remains like that and react with some intermediate to form ssome bases..... NH3 is basic in nature so it takes H+ to form NH4+.......
