* Homogeneous Mixture: A homogeneous mixture has a uniform composition throughout. This means that the components are evenly distributed and indistinguishable from one another.
* Heterogeneous Mixture: A heterogeneous mixture has components that are not evenly distributed and can be easily distinguished from one another.
Why salt is homogeneous:
* Ionic Compound: Table salt is an ionic compound formed by the strong electrostatic attraction between sodium (Na+) ions and chloride (Cl-) ions.
* Uniform Structure: These ions are arranged in a highly ordered and repeating crystalline structure. This uniform arrangement makes the composition of salt consistent throughout.
* Dissolving in Water: When salt dissolves in water, the ions become surrounded by water molecules, but they remain evenly distributed and do not form separate phases.
In summary: Salt is a homogeneous mixture because it has a uniform composition and the components are evenly distributed, making it impossible to distinguish between them.
