Crystal structures

NaCl (Sodium chloride)

Melting point- 801C




What happens when NaCl is dissolved in water?

Why is the freezing point lowered when salt is added?
    this is caused because the salt molecules are dispersed between the water molecules and make it difficult for the water molecules to come together and become a crystal structure.

CaCO3 (Calcium carbonate)
Melting point- 1330C
