* Solid: This is the most common phase of salt, where the sodium and chloride ions are arranged in a regular, crystalline structure.

* Liquid: Salt melts at 801°C (1474°F) and becomes a liquid.

* Gas: At even higher temperatures, salt can vaporize and exist as a gas.

It's important to note that there are also some intermediate phases of salt that are less common. For example, under high pressure, salt can exist in a number of different crystal structures.

Overall, while salt is most familiar as a solid, it can exist in three main phases depending on the temperature and pressure.
