$ceNH3 + H2O -> NH4OH$
So That"s why, they claimed that it is a base.
You are watching: Is nh3 an acid or a base
But in a neutralization reaction, discussed by our teacher,
Acid + base = Salt + water
So, if $ceNH3$ is a base then,it need to be,
Acid + $ceNH3$ = Salt + Water
But it does not happen. Once reacting v acid, the doesn"t develop water.
$ceNH3 + HCl -> NH4Cl$
$ceNH3 + H2SO4 -> (NH4)2SO4$
So the is not creating water in the neutralization reaction. Hence, I"m confused whether it is base or not.
Your difficulties are caused by using the Arrhenius theory, i m sorry is based on electrolytic dissociation.
According to the Arrhenius definition, acids room compounds the dissociate and also release hydrogen ion $(ceH+)$ into the solution:$$ceHCl -> H+ + Cl-$$Bases are defined as compounds that dissociate and release hydroxide ion $(ceOH-)$ right into the solution:$$ceNaOH -> Na+ + OH-$$The assets of a neutralization reaction of one acid v a base room a salt and also water:$$ceHCl + NaOH -> NaCl + H2O$$This definition works for metal hydroxides such as $ceNaOH$, which can exist as pure compounds. However, the doesn’t work for bases such together $ceNH3$.
In stimulate to resolve this difficulty for $ceNH3$, the fictitious compound “ammonium hydroxide” $ceNH4OH$ was proposed (see also this associated answer). Assuming this formula, the Arrhenius meanings of bases and also neutralization reactions job-related again:$$ceNH4OH -> NH4+ + OH-$$$$ceHCl + NH4OH -> NH4Cl + H2O$$However, ammonium hydroxide cannot be isolated; the fictitious solid compound does no exist. Nevertheless, the misleading timeless name “ammonium hydroxide” is quiet widely provided for services of ammonia in water.

In order come really settle your difficulties with $ceNH3$, you need to switch native the an interpretation of bases according to the Arrhenius theory to the meaning of bases according to the Brønsted–Lowry theory.
