In chemistry – what is a “mixture”
WebA mixture is a physical blend of two or more components, each of which retains its own identity and properties in the mixture. Only the form of the salt is changed when it is dissolved into water. It retains its composition and properties. A homogeneous mixture is a mixture in which the composition is uniform throughout the mixture. WebOct 12, 2024 · In chemistry, a mixture is defined as a physical combination of two or more substances that do not produce a chemical reaction. This means that chemical bonds are neither created nor broken between atoms. The individual constituents therefore retain their unique chemical properties.
