Answer 1

Yes, each crystal is a homogeneous latice of + and - ions. The air between makes the total filling of your table salt dispenser heterogeneous.

Yes, common salt (sodium chloride) is a homogeneous mixture because its composition is uniform throughout. When you dissolve salt in water, the salt ions are evenly distributed, resulting in a homogeneous solution.

Answer 3

Common salt is a compound (NaCl), not a mixture; and of course is homogeneous, after refining.
