Sodium chloride is only a solid, a compound.
When salt dissolves in water, the number of observable phases is two: the solution of salt and water. The salt crystals disappear as they dissolve in the water, resulting in a homogenous mixture.
In mixtures of salt and water, typically two phases are observed: a solid phase of salt crystals and a liquid phase of water.
Salt primarily exists in three phases: solid, liquid, and gas. In its most common form, sodium chloride (table salt) is a solid at room temperature. When dissolved in water, it exists in a liquid phase. At high temperatures, salt can vaporize and enter a gaseous phase, although this is less common in everyday contexts.
Only one phase, a homogeneous solution.

The maximum number of phases that can be in mutual equilibrium is three.

Salt water is a heterogenous mixture because it consists of two or more distinct phases (solute particles dispersed in a solvent).
Physical phases of matter are not limited to three. Phases of the moon are not limited to three. Phases of a wave form are not limited to three. What phase is limited to three?
Salt primarily exists in solid form as sodium chloride (NaCl) at room temperature. When dissolved in water, it dissociates into its constituent ions, sodium (Na⁺) and chloride (Cl⁻), creating an aqueous solution. When heated to high temperatures, salt can melt into a liquid phase and, at even higher temperatures, can vaporize into a gaseous state. These phases—solid, liquid, and gas—demonstrate salt's ability to transition based on temperature and pressure conditions.
