Chapter Overview
Salts are ionic compounds formed when positive ions and negative ions combine in a fixed ratio. They are commonly produced during reactions between acids and bases, acids and metals, or acids and carbonates. Salts are important in daily life, industry, agriculture and laboratory chemistry.
In this chapter, students learn how ions are arranged in salts and why ionic compounds usually have high melting points. The strong electrostatic forces between oppositely charged ions hold the crystal lattice together. These forces also explain why ionic compounds are hard and why a large amount of energy is needed to melt them.
The chapter also explains electrical conduction and solubility of salts. Ionic compounds conduct electricity when molten or dissolved in water because ions become mobile. Students also study soluble and insoluble salts and learn methods for preparing soluble salts in the laboratory.
