Why is ammonia considered to be a base?

Answer 1

A base is a proton acceptor. On the pH scale, bases have a pH greater than 7.

Ammonia (NH3) is a base because it can accept protons from water (H20) forming negatively charged hydroxide ions (OH-).

NH3 + H2O = NH4OH = NH4+ + OH-

Answer 2

When ammonia dissolves in water it is believed that the ammonia accepts a hydrogen from the water due to the lone pair of electrons of the nitrogen in ammonia, this leaves an hydroxide ion that allows the solution to be basic.

NH3(aq) + H2O(l) --> NH4+(aq) + OH-(aq)

Answer 3

This has got to do with the way ammonia acts when exposed to other elements. An example i will use is water. The first thing you need to know is this. Elements can undergo what is know as dissociation. For example in all water(H2O) it will be found that you also can find H+ and OH- floating in the solution. this is a natural thing water and most molecules will do as a solution. this is in what is called equilibrium with the h2o molecule. When ammonia is placed in water it will actually take the H+ ions from the solution and form NH4+. By taking the H+ ion the ammonia is leaving an excess of OH- (hydroxide) ions. The concentration of OH- ions is also used to calculate the pH level of a solution. The presence of the OH- ion will indicate a basic solution and due to the fact that the ammonia has created an excess of them it is seen that ammonia is basic as a solution

Answer 4

It has a lone pair.So it can donate electrons.

Answer 5

well the bonds make a relationship towards eastenders

if u do this it makes an omlette

Answer 6

NH3 has a lone pair.So it can donate the lone pair and act as a base.

Answer 7

Ammonia is dissolves in water. It makes water basic.

Answer 8

Ammonia dissolved in water is ammonium hydroxide - NH4OH.

Answer 9

Yes it dissolve in water .It is a basic compound

Answer 10

Ammonia is amphoteric because the nitrogen atom has a lone electron pair.
