Heterogeneous mixtures are not uniform. Mixtures can either be homogeneous or heterogeneous in nature depending on how uniform the resulting mixture is and whether or not you can determine the separation between the substances and elements used to make the mixture. Sodium chloride solid is not a mixture. 1. Once you open the bottle, bubbles appear in the liquid. Thus, we say it is a pure substance. Salt easily dissolves in water, but salt water cannot be classified as a substance because its composition can vary. Air is a homogeneous mixture. What Is the Most Abundant Salt in the Ocean?
