Water is dissolved into n-butanol (a polar liquid). Which is the second step at the molecular level as water dissolves into n-butanol?


A. n-Butanol mixes with water.

B. Water molecules are carried into n-butanol.

C. n-Butanol molecules surround water molecules.

D. n-Butanol molecules are attracted to the surface of the water molecules.



Answer :

Answer:

C. n-Butanol molecules surround water molecules.

Explanation:

Because both liquids are polar, they can be mixed (polar dissolves polar, and nonpolar dissolves nonpolar). N-Butanol is the solvent, so it has a large amount in the solution, and water is the solute. When a liquid-liquid solution is placed, the solvent surrounds the molecules of the solute, so the solute is dissociated in the solution.

Then, the n-Butanol molecules surround the water molecules.
