Most of the things that we use in our day-to-day life are in the form of mixtures. Pure substances are rare. For example, the dissolved sugar can be separated from its solution by some physical process (evaporation or distillation). However, sugar is itself a substance and cannot be separated by physical processes into its constituents. Similarly, common salt (sodium chloride), iron, mercury, calcium oxide, hydrochloric acid are substance.<br \/>\n<img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-121285\" src=\"https:\/\/www.aplustopper.com\/wp-content\/uploads\/2016\/09\/What-are-the-types-of-Pure-substances-and-Mixtures-1.png\" alt=\"What are the types of Pure substances and Mixtures 1\" width=\"871\" height=\"326\" srcset=\"https:\/\/www.aplustopper.com\/wp-content\/uploads\/2016\/09\/What-are-the-types-of-Pure-substances-and-Mixtures-1.png 871w, https:\/\/www.aplustopper.com\/wp-content\/uploads\/2016\/09\/What-are-the-types-of-Pure-substances-and-Mixtures-1-300x112.png 300w, https:\/\/www.aplustopper.com\/wp-content\/uploads\/2016\/09\/What-are-the-types-of-Pure-substances-and-Mixtures-1-768x287.png 768w\" sizes=\"(max-width: 871px) 100vw, 871px\" \/><br \/>\n<strong><span style=\"color: #993366;\">Pure substances<\/span><\/strong><\/p>\n<ul>\n<li>A pure substance consists of a single type of particles.<\/li>\n<li>Pure substances are always homogeneous.<\/li>\n<li>All the elements and compounds are pure substances because they contain only one kind of particles.<\/li>\n<li>A pure substance cannot be separated into other kinds of matter by any physical process.<\/li>\n<li>A pure substance has a fixed composition as well as a fixed boiling point and melting point.<\/li>\n<\/ul>\n<p><strong><b>Ex. <\/b><\/strong>\u00a0\u00a0\u00a0\u00a0 Hydrogen, Oxygen, Copper, Gold, Silver.<\/p>\n<p>Pure substances can be divided into <strong>two types<\/strong>.<\/p>\n<ol>\n<li><strong><b><a href=\"https:\/\/www.aplustopper.com\/classification-elements\/\">Elements<\/a> \u00a0<\/b><\/strong><\/li>\n<li><a href=\"https:\/\/www.aplustopper.com\/characteristics-compound\/\"><strong><b>Compounds<\/b><\/strong><\/a><\/li>\n<\/ol>\n<p><span style=\"color: #993366;\"><strong><b>Mixtures<\/b><\/strong><\/span><br \/>\nA mixture is a substance which consists of two or more elements or compounds not chemically combined together.
