Why is ammonia basic in natue?

Answer 1

The NH3 molecule has a large dipole moment, and this is consistent with its geometry, a trigonal pyramid.

The electronic arrangement in nitrogen obeys the octet rule. The four pairs of electrons (three bonding pairs and one non-bonding lone pair) repel each other, giving the molecule its non-planar geometry. The H–N–H bond angle of 107 degrees is close to the tetrahedral angle of 109.5 degrees. Because of this, the electronic arrangement of the valence electrons in nitrogen is described as sp3 hybridization of atomic orbitals.

The polarity of NH3 molecules and their ability to form hydrogen bonds explains the chemical reaction that occurs when ammonia dissolves in water. In aqueous solution, ammonia acts as a base, acquiring hydrogen ions from H2O to yield ammonium and hydroxide ions.


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

The production of hydroxide ions when ammonia dissolves in water gives aqueous solutions of ammonia their characteristic alkaline (basic) properties. The double arrow in the equation indicates that an equilibrium is established between dissolved ammonia gas and ammonium ions. Not all of the dissolved ammonia reacts with water to form ammonium ions. A substantial fraction remains in the molecular form in solution. In other words, ammonia is a weak base.

Answer 2

Ammonia (NH3) is more basic as H2O is neutral Ph = 7

Answer 3

NH3 or ammonia is base.
if a molecule accepts H+ or has OH like NaOH is base
ammonia accepts and becomes NH4+

Answer 4

It readily accepts a proton.

Answer 5

because it is in urine.
