Question
Chapter 15, Problem 65E
Interpretation Introduction
Interpretation:
The error in the molecular picture of a soap molecule in water is to be identified.
Concept Introduction:
Polar molecules attract each other, whereas non-polar molecules are not attracted by them.
Polar molecules do not mix with non-polar molecules.
Polar molecules mix with other polar molecules, while non-polar molecular mix with other non-polar molecules only.
Soap molecules have polar and non-polar sides, which helps in the dissolution of non-polar molecules to the non-polar side and polar molecules to the polar side.

The chemist mixes 2.5 g of the blue crystals with 2 L water to produce a clear, blue liquid. When filtered through filter paper, the filtered liquid retains the same blue color. How can these observations be explained? A Materials pass through filter paper only when the paper is wet. B. The copper sulfate crystals slide more easily through the filter paper when water is present. The copper sulfate reacts with water molecules to form a new substance that can pass through filter paper. Water acts as a solvent to break up copper sulfate into individual ions, which allows them to pass through the filter paper.arrow_forward1. Seawater is composed of salt, sand, and water.
