What is the chemical equation for the reaction of ammonia and water?
When ammonia is dissolved in water, it undergoes the following reversible reaction. NH3(aq)+H2O(l) → NH4+ (aq)+ OH- (aq). In this reaction, the water molecule is donating a proton to the ammonia molecule. The resulting products are the ammonium ion and the hydroxide ion.
What is the chemical reaction of ammonium NH3 with water?
Chemical reactivity of ammonia NH3 + H2O ⇌ NH4+ + OH− These aqueous solutions of ammonia are basic and are sometimes called solutions of ammonium hydroxide (NH4OH). The equilibrium, however, is such that a 1.0-molar solution of NH3 provides only 4.2 millimoles of hydroxide ion.

What is ammonia a chemical reaction?
The NH3 molecule has a large dipole moment, and this is consistent with its geometry, a triangular pyramid. However, a chemical reaction also 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.
What happens to ammonia in water?
Ammonia has alkaline properties and is corrosive. Ammonia gas dissolves easily in water to form ammonium hydroxide, a caustic solution and weak base.
What happens when you mix ammonia and water?
Ammonia gas dissolves easily in water to form ammonium hydroxide, a caustic solution and weak base.
Is ammonia present in water?
Ammonia is a colorless, pungent gaseous compound of hydrogen and nitrogen that is highly soluble in water. It is a biologically active compound found in most waters as a normal biological degradation product of nitrogenous organic matter (protein).
Why is ammonia added to water?
Ammonia is a colorless, pungent gaseous compound of hydrogen and nitrogen that is highly soluble in water. The addition of ammonia enhances the formation of chloramines (which may create objectionable tastes), and it reduces the formation of chlorination by-products which may be carcinogenic.
What happens when ammonia is mixed with water?
5 Answers. As ammonia dissolves in water, it reacts with water to form ammonium ions (NH4+) and hydroxide ions (OH-): Therefore, the hydroxyl ions lend the properties of a base to aqueous ammonia solution, meaning that added to water, the ammonia gas acts as a base.
How does ammonia react with water?
Ammonia is a weak base and is able to accept a proton. When it reacts with water, water would act as an acid and donates a proton to ammonia, allowing ammonia to be protonated to form ammonium ion. Hydroxide ions would then be produced as water loses its H+ ion to ammonia.
What is the equation for making ammonia?
The balanced equation for the reaction of nitrogen and hydrogen that yields ammonia is N2 +3H2 produces 2NH3. This equation means that it requires one molecule of nitrogen gas to react with three molecules of hydrogen gas to form two molecules of ammonia. Ammonia is a compound that is colorless and has a pungent odor.
What is the chemical formula for ammonia?
The formula of the chemical compound Ammonia is NH3
