Question

Give reasons for the following:
The aqueous solution of ammonia conducts electricity.

Answer 1

Before solving this question, we should know what are solutions. The combining of substances by the means of intermolecular forces or ionic forces is known as a solution. They can get separated by physical change like boiling, boiling helps to away the solvent. They are not combined chemically and can only be separated by a chemical change. They are also combinations of substances that are not chemically combined.

Complete answer:
Aqueous solution- The solution is known as aqueous when a solute is dissolved in water. Example- Salt in water, sugar in water, etc.
Ammonia: It is a colorless gas that has a chemical formula $N{{H}_{3}}$. It comprises hydrogen and nitrogen. Ammonium hydroxide is its aqueous form. It is an inorganic compound that has a pungent smell. It is dangerous and caustic in its concentrated form. It is lighter than air and has a density of 0.769 $Kg/{{m}^{3}}$at STP. It occurs naturally in many parts of the environment like the soil, the air, and vegetation. The human body also creates ammonia naturally while breaking down protein-containing food into amino acids. The ammonia is then converted into urea.
STP refers to the abbreviation for Standard temperature and Pressure in chemistry. When we do calculations on gases like gas density. 273 K/ 0$^{\circ }C$/ 32 $^{\circ }F$is the standard temperature and 1 atm pressure is the standard pressure. It is the freezing point of pure water at sea level atmospheric pressure. One mole of gas occupies 22.4 L of molar volume at STP.
Ammonia when dissolved in water forms aqueous ammonia, it breaks into ions that help in the conductance of electricity.
$N{{H}_{3}}+{{H}_{2}}O\to N{{H}_{4}}OH\rightleftharpoons NH_{4}^{+}+O{{H}^{-}}$

Note:
Uses of Ammonia-
It is used as a refrigerant.
It is used in the fermentation industry.
It is used as fertilizer.
It is used as a cleaner in the household.
It is used to adjust pH in the fermentation process.
