Is Salt Water a Compound? - Techiescientist Homogeneous & Heterogeneous Mixture: Homogeneous mixture: composition of the mixture is uniform throughout. It is only when the water has other impurities or substances in it (as in the case of seawater), has a particularly insoluble kind of salt, has a cooler temperature or has become saturated that the mixture might lean towards becoming heterogeneous. As NaCl completely dissolves in water, aqueous sodium chloride is a homogeneous mixture, thus giving a single visible step.
