What are the scientific physical properties of sodium chloride?

Answer 1

Physical properties are things like boiling point / melting point

here is one to do with sodium chloride

The melting point of pure salt is 800.8°C. The boiling point of salt is 1465°C.

Answer 2

Some of the physical properties of sodium chloride can be determined by simple observation: it is a cubic crystal, it dissolves in water, and it tastes salty (but do not taste chemical unless told to do so by your instructor!). Other properties require lab equipment: it's melting point, it's solubility constant, it's density, etc.

Answer 4

It is a crystal, so it has a regular repeating structure, which is a cube. Im just going to come oit and say it, its tanle salt.
