Which of the following best represent a molecular-scale view of an ionic compound in aqueous solution? Explain.

Short Answer

Expert verified

(C) represents the best molecular-scale view of an ionic compound in aqueous solution.

Step by step solution

01

Ionic bond

Ionic bond, also called electrovalent bond. Ions in a chemical compound can create ionic bonds, a sort of linkage, through electrostatic attraction.

Such a bond is formed when the valence electrons of one atom are transferred permanently to another atom.

02

Molecular view 

The positively charged ions surrounded by negatively charged ion or vice-versa is the best representation of molecular view.

Molecular scale view (A) has only positively charged ions.

Molecular-scale view (B) has both positively and negatively charged ions but they are not surrounded by each other.

Molecular scale view only (C) represents the best molecular-scale view. Because in molecular-scale view (C) has positively charged ions surrounded by negatively charged ions or vice versa.
