Detailed explanation-1: -When salt is mixed with water, the salt dissolves because the covalent bonds of water are stronger than the ionic bonds in the salt molecules.

Detailed explanation-2: -Water is called the “universal solvent” because it is capable of dissolving more substances than any other liquid. This is important to every living thing on earth. It means that wherever water goes, either through the air, the ground, or through our bodies, it takes along valuable chemicals, minerals, and nutrients.

Detailed explanation-3: -In a solution, the substance which is dissolved is called a solute and the substance in which the solute is dissolved is called a solvent. To obtain salt solution, salt is mixed in water and hence salt is the solute and water is the solvent.

Detailed explanation-4: -For example, in a solution of salt in water, the solute is salt, and solvent is water. Solutions come in all phases, and the solvent and the solute do not have to be in the same phase to form a solution (such as salt and water).

Detailed explanation-5: -Salt dissolves in water to form salt solution.
