Question

Interaction between the solute and solvent molecules is known as:
A) solute
B) solvent
C) aqueous solution
D) solvation

Answer 1

Hint:We also know that the amount of solute and solvent dissolved in the given amount of solvent depends on the nature of the solute and solvent. The solute-solvent interaction generally depends on the “Like dissolves like” rule. This is a general rule for the solubility of solute in solvent.

Complete step by step answer:
We must remember that the polar solvents more readily dissolve the polar solutes but cannot dissolve the non-polar solutes. Thus the sodium chloride salt which is an ionic compound readily dissolves in the water which is a polar solvent. However, it is not readily soluble in ether, benzene, or hexane which are non-polar solvents. Now according to the solute-solvent interaction rule, the non-polar solute dissolves in the non-polar solvent. It cannot dissolve the polar or ionic solutes.

Solute: The substance which is being dissolved in solvent to make a solution is known as solute. It is present in lesser quantity than solvent within the solution.
Solvent: The component of a solution in which solute is being dissolved is called a solvent. It is present in more quantity than solute in solution.
For example: If we take a solution of salt-water. Then during this solution salt is solute and water may be a solvent as salt is being dissolved in water and salt is present in lesser quantity than water in the solution.

Solvation: Solvation is an attraction and association between the molecules in the solvent and the ions of solute. As ions dissolve within a solvent they spread out and become surrounded by solvent molecules. Solvation is the process of surrounding solute and solvent.

So the answer to the present question is option D i.e. Solvation.

Note: Non polar solvents do not form the hydrogen bonding with the solvent. But they dissolve the solute by weak van der Waals force among the solute and solvent.
