1. Is table salt a typical ionic compound? Explain? 2. Describe the melting points of ionic compounds? 3. Do ionic compounds conduct electricity?
Understand the Problem
These are three separate chemistry based questions: The first question asks whether table salt is a typical ionic compound and to further explain this. The second question asks us to describe the melting point of ionic compounds. The third question asks whether ionic compounds conduct electricity. The response to each of these questions requires an understanding of chemical bonds, ion formation, and electrical conductivity in solutions.
Answer
Yes, table salt is a typical ionic compound. Ionic compounds have high melting points and conduct electricity when dissolved or melted, but not in solid form.
Yes, table salt (sodium chloride) is a typical ionic compound because it is formed through the transfer of electrons between a metal (sodium) and a nonmetal (chlorine), resulting in a crystal lattice structure. Ionic compounds generally have high melting points because a lot of energy is required to break the ionic bonds in the crystal lattice. Ionic compounds do not conduct eletricity in solid form, but will conduct when dissolved in water or melted.

More Information
The melting point of sodium chloride is 801°C. The boiling point of sodium chloride is 1,413°C.
Tips
Many students may not specify the conditions under which ionic compounds conduct electricity. Ionic compounds only conduct electricity when dissolved in water or melted.
