Only one type of molecule or ion-pair.


Ethanol - consists only of #CH_3CH_2OH#. Sodium chloride consists only of NaCl. Water consists only of #H_2O#.

But mixtures consist of more than one type of molecule of ion pair. Iron filings mixed with sodium chloride - contains Iron (Fe) and also sodium chloride (NaCl).
