  2. Dispersion (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Dispersion_(chemistry)

    A colloid is a heterogeneous mixture where the dispersed particles have at least in one direction a dimension roughly between 1 nm and 1 μm or that in a system discontinuities are found at distances of that order. [8] A suspension is a heterogeneous dispersion of larger particles in a medium. Unlike solutions and colloids, if left undisturbed ...

    en.wikipedia.org/wiki/Josiah_Willard_Gibbs

    Josiah Willard Gibbs (/ ɡɪbz /; [ 2 ] February 11, 1839 – April 28, 1903) was an American scientist who made significant theoretical contributions to physics, chemistry, and mathematics. His work on the applications of thermodynamics was instrumental in transforming physical chemistry into a rigorous deductive science.

  4. Suspension (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Suspension_(chemistry)

    Suspension (chemistry) A suspension of flour mixed in a glass of water, showing the Tyndall effect. In chemistry, a suspension is a heterogeneous mixture of a fluid that contains solid particles sufficiently large for sedimentation. The particles may be visible to the naked eye, usually must be larger than one micrometer, and will eventually ...

  5. Mixture - Wikipedia

    en.wikipedia.org/wiki/Mixture

    A mixture is a material made up of two or more different chemical substances which can be separated by physical method.It is an impure substance made up of 2 or more elements or compounds mechanically mixed together in any proportion. [ 1 ] A mixture is the physical combination of two or more substances in which the identities are retained and ...

  6. Separation process - Wikipedia

    en.wikipedia.org/wiki/Separation_process

    t. e. A separation process is a method that converts a mixture or a solution of chemical substances into two or more distinct product mixtures, [ 1 ] a scientific process of separating two or more substances in order to obtain purity. At least one product mixture from the separation is enriched in one or more of the source mixture's constituents.

  7. Homogeneity and heterogeneity - Wikipedia

    en.wikipedia.org/wiki/Homogeneity_and_heterogeneity

    Homogeneity and heterogeneity; only ' b ' is homogeneous Homogeneity and heterogeneity are concepts relating to the uniformity of a substance, process or image.A homogeneous feature is uniform in composition or character (i.e. color, shape, size, weight, height, distribution, texture, language, income, disease, temperature, radioactivity, architectural design, etc.); one that is heterogeneous ...

  8. Chemical substance - Wikipedia

    en.wikipedia.org/wiki/Chemical_substance

    A chemical substance is a unique form of matter with constant chemical composition and characteristic properties. [1][2] Chemical substances may take the form of a single element or chemical compounds. If two or more chemical substances can be combined without reacting, they may form a chemical mixture. [3]
