Question

Nitrogen dioxide is dissolved in water to produce:
(A) $ HN{O_3} $ and $ HN{O_2} $
(B) Only $ HN{O_3} $
(C) Only $ HN{O_2} $
(D) $ HN{O_2} $ and $ {N_2} $

Answer 1

Hint : Any chemical compound when dissolved in water is called aqueous solution. Substances that dissolve in water to yield ions are called electrolytes. Gases dissolve in water to form solutions. This dissolution is an equilibrium process for which an equilibrium constant can be written.

Complete Step By Step Answer:
Nitrogen dioxide gas reacts with water and produces nitric acid and nitrogen monoxide. The resulting chemical reaction is as follows,
 $ 2N{O_2} + {H_2}O \to HN{O_3} + HN{O_2} $
This reaction is a redox reaction. When ionic compounds dissolve in water, the ions in the solid separate and disperse uniformly throughout the solution because water molecules surround and solvate the ions, reducing the strong electrostatic forces between them. This process represents a physical change known as dissociation.
Hence the correct option is A. $ HN{O_3} $ and $ HN{O_2} $ .

Additional Information:
Metals react with water and produce a metal oxide and hydrogen gas. Metal oxides that are soluble in water dissolve in it to further form metal hydroxide. Non-metals do not react with water (or steam).
Sugar, sodium chloride, and hydrophilic proteins are all substances that dissolve in water. Oils, fats, and certain organic solvents do not dissolve in water because they are hydrophobic.

Note :
Nitrogen dioxide ( $ N{O_2} $ ) is a gaseous air pollutant composed of nitrogen and oxygen and is one of a group of related gases called nitrogen oxides. $ N{O_2} $ forms when fossil fuels such as coal, oil, gas or diesel are burned at high temperatures. The gas which is most soluble in water is $ N{H_3} $ because of hydrogen bonding with water.
