From a modern point of view, compounds are contrasted with elements of which they are composed, and the two categories combine to give the category of substances. Mixtures, on the other hand, might be understood to contrast with pure substances (substances in isolation), so that mixtures are ...
Unlike compounds, mixtures consist of two or more substances that do not combine chemically and can usually be separated by simple mechanical means such as filtering or evaporation. Mixtures include alloys, such as steel (iron with carbon), as well as solutions, such as salt dissolved in water...

623 The medicinal preparations range from simple inorganic salts to bismuth complexes of carboxylic, hydroxo- and amino-carboxylates, of which the colloidal bismuth subcitrate is a widely used example. Many of the preparations are mixtures of complexes and the chemical speciation is ill-defined. ...

Mixtures are composed of pure substances and elements, but unlike compounds these substances retain their own chemical identities and properties. Mixtures can be homogeneous or heterogeneous. Homogeneous mixtures are the same throughout and are called solutions. Heterogeneous mixtures don't have uniform ...
