Pure Substance 👌 : Concept, types, examples and mixtures 🔥

What is a pure substance? Pure substances are those that have a fixed and defined chemical composition , that is, that does not vary regardless of the physical conditions in which said substance is found. In other words, pure substances remain chemically unaltered (their chemical structure does not change) in their different states of aggregation . Using physical separation methods, pure substances cannot be decomposed into simpler substances, nor into their constituent elements. To decompose a pure substance it is necessary to use chemical methods by which the substance is transformed into other substances, or into the elements that compose it. In addition, a pressure and temperature specific, can be played for the pure substances, physical properties such as density , the boiling point and melting point . A clear example of a pure substance is water , simple and abundant, which can exist in liquid , gaseous or solid form , but it will always be composed of the same chemical elements and will always respond the same to the same conditions of temperature and pressure. On the other hand, if we add salt, sugar and other substances, we alter its physical properties and it is no longer a pure substance. In nature there is no totally pure substance, that is, substances always have some impurities added. Currently, with scientific and technological advances, it has been possible to purify substances to obtain high degrees of purity. ▬ ▬ Do not forget to press on the like 👍 button and share our video if you like the video ❤ We are happy to know your opinions in the comments section ⚈ To subscribe to the channel click here 👇 https://bit.ly/3yrNChk ⚈ For more videos 👇 https://bit.ly/2WZt6H5 ▬ ▬ Navigate in the video: ⏩ What is a pure substance? ⏩ Types of pure substances ⏩ Examples of pure substances ⏩ Mixtures ▬ ▬ ▬ For more information about Pure Substance : ▬ ▬ ▬ ⚈ Archive of previous videos: ••• ••• ▬ ▬ ▬ Facebook Page :   / know-think-tube-131441039107267   Facebook Group : Reddit Community :   / knowandthinktube   TWITTER: ▬ ▬ ▬ ▬ ▬ © Copyright know & think Tube Channel.
