Oct 11, 2011 · 3.While both a pure substance and a homogeneous mixture have uniform compositions throughout, it is impossible to extract the components of a pure substance while the pure substances that make up a homogeneous mixture can be extracted because they retain their properties even when mixed together.
A homogeneous mixture is a combination of two or more substances that are evenly distributed throughout, resulting in a uniform composition. Examples include saltwater and air. On the other hand, a pure substance is a single type of matter that has a fixed composition and distinct properties. It can be either an element, such as gold or oxygen ...
Substances which have a specific composition and cannot be separated into any constituents are called pure substances. Pure substances are further divided into elements and compounds. The combination of two or more pure substances is called a mixture. Mixtures can be classified into two types viz. heterogeneous and homogeneous mixtures.
Jul 20, 2022 · In a homogeneous mixture, on the other hand, any sample that you examine will have exactly the same composition as any other sample.
