is sodium chloride a homogeneous or heterogeneous mixture

Unlike homogeneous mixtures, however, heterogeneous mixtures usually have larger particles that end up forming a separate layer from the base if you leave the mixture to rest for a while. Homogeneous mixtures, often called solutions, form because a solute and a solvent experience similar intermolecular interactions.
