Detailed Summary
There are two types of mixtures: General Properties of Mixtures Mixtures are made up of two or more substances that are not chemically combined with each other. The properties of mixtures are listed below. The components of a mixture each keep their original properties. The separation of components can be easily done. The proportion of the components is variable. Examples of Mixtures Crude oil: A mixture of organic compounds (mainly hydrocarbons) Seawater: A mixture of various salt and water. Air: a mixture of various gases like oxygen, carbon dioxide, nitrogen, argon, neon, etc. Ink: A mixture of coloured dyes. Gunpowder: A mixture of sulfur, potassium nitrate and carbon. KE There are two main types of mixtures: homogeneous mixtures and heterogeneous mixtures. The types of mixtures are discussed below. Heterogeneous Mixture What is a Heterogeneous Mixture. A mixture of sand mixed with salt is an example of a heterogeneous mixture. Heterogeneous mixtures possess different properties and compositions in various parts i.
