Chapter 13, Problem 26QRT

Interpretation Introduction

Interpretation:

Dissolving an ionic solid in water has to be described; at least three positive ions, three negative ions, and a dozen or so water molecules in the vicinity of the ions have to be sketched.

Concept introduction:

Like dissolves like principle:‘Like dissolves like’ principle says that polar compounds including ionic compound should be more soluble in polar solvent.  Likewise, non–polar compound should be more soluble in non–polar solvent.

Polar molecule: Polar molecules have large dipole moments.

Non-Polar molecules: Non-polar molecules have bonded atoms with similar electronegativity results to have zero dipole moments.
