D.${\text{N}}{{\text{H}}_3},{{\text{H}}^ + },{\text{NO}}_3^ - $
E.${{\text{N}}^{5 + }},{{\text{N}}^{3 - }},{{\text{H}}^ + },{{\text{O}}^2} - $

Answer 1

Hint: An ionic compound is a chemical complex made up of ions kept together by electrostatic forces known as ionic bonding in chemistry. Overall, the chemical is neutral, although it contains both positively and negatively charged ions known as cations and anions.

Complete answer:
If the ionic compound is soluble in a solvent, the solvent can be evaporated from the electrolyte solution to yield a solid compound. The ions do not go into the vapour when the solvent evaporates, but rather stay in the residual solution, where they nucleate and crystallise into an ionic compound when sufficiently concentrated. This process is common in nature and is responsible for the creation of evaporite minerals. Another approach for recovering a chemical from solution is to saturate a solution at a high temperature, then reduce the solubility by lowering the temperature until the solution is supersaturated and the solid compound nucleates. Evaporation, precipitation, or freezing can all be used to make ionic compounds from their component ions. Reactive metals, such as alkali metals, can generate an ionic product by reacting directly with strongly electronegative halogen gases. They can also be made as a result of a high-temperature solid-solid reaction. Ionic compounds are often rigid and brittle, with high melting and boiling temperatures. They are virtually always electrically insulating as solids, but when melted or dissolved, the ions are mobilised, and they become extremely conductive.
The ions contained in the ionic solid ammonium nitrate $N{H_4}N{O_3}$ are ammonium ${\text{NH}}_4^ + $, also nitrate ${\text{NO}}_3^ - $. Between oppositely charged ions, there is a strong electrostatic attraction.

Hence option A is correct.

Note:
Ammonium nitrate, sometimes known as $N{H_4}N{O_3}$, is a chemical compound having the formula $N{H_4}N{O_3}$. It's a white crystalline substance made up of ammonium and nitrate ions. Although it does not form hydrates, it is very soluble in water and hygroscopic as a solid. It is mostly used as a high-nitrogen fertiliser in agriculture. In 2017, global output was predicted to be 21.6 million tonnes.
