Why do ionic compounds dissolve in water?

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 molecule is neutral, although it contains both positively and negatively charged ions known as cations and anions. Ionic compounds are usually 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.

Complete answer:
In the same way that like dissolves in the same way that like dissolves in the same In a polar solvent, the polar component dissolves. Water, the universal solvent, is the greatest example of a polar solvent since it can dissolve a wide range of substances.
When an ionic compound is mixed with water, the polarity of the water around it causes the ionic component to break down. The electronegative element oxygen is found in water, whereas the electropositive element hydrogen is found in nature. The electropositive metal ion will be attracted to the electronegative oxygen atom, whereas the electropositive hydrogen atom will be attracted to the electronegative chlorine ion.
The following equation depicts the dissociation of sodium chloride in water.
\[NaCl\xrightarrow{{{H}_{2}}O}N{{a}^{+}}+C{{l}^{-}}\]
Ionic chemicals dissociate and dissolve in water in this manner.
Ionic compounds dissolve in water if the energy released by the ions when they contact with water molecules is sufficient to offset the energy necessary to break the ionic bonds in the solid and to separate the water molecules so that the ions may be put into solution.

Note:
Ionic compounds become soluble when they dissolve in water, and because water is dipolar, it dissolves ionic polar compounds as well. When the ion – ion relationship weakens, the ion – water molecule contact kicks in and becomes strong, allowing the ionic compound to dissolve, whereas in the case of insoluble compounds, the water and ion interactions are weak.
