  2. Suspension (chemistry) - Wikipedia

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

    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 settle , although the mixture is only classified as a suspension when and while the particles have ...

  3. Photographic emulsion - Wikipedia

    en.wikipedia.org/wiki/Photographic_emulsion

    Photographic emulsion is a fine suspension of insoluble light-sensitive crystals in a colloid sol, usually consisting of gelatin. The light-sensitive component is one or a mixture of silver halides: silver bromide, chloride and iodide. The gelatin is used as a permeable binder, allowing processing agents (e.g., developer, fixer, toners, etc ...

  4. Colloid - Wikipedia

    en.wikipedia.org/wiki/Colloid

    A colloid is a mixture in which one substance consisting of microscopically dispersed insoluble particles is suspended throughout another substance. Some definitions specify that the particles must be dispersed in a liquid, [1] while others extend the definition to include substances like aerosols and gels.

  5. 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 ...

    Red acrylic paint squeezed from a tube Example of acrylics applied over each other. Experimental pictures with "floating" [a] acrylic paint Acrylic paint is a fast-drying paint made of pigment suspended in acrylic polymer emulsion and plasticizers, silicone oils, defoamers, stabilizers, or metal soaps.

  7. Homogeneity and heterogeneity - Wikipedia

    en.wikipedia.org/wiki/Homogeneity_and_heterogeneity

    A heterogeneous mixture is a mixture of two or more compounds. Examples are: mixtures of sand and water or sand and iron filings, a conglomerate rock, water and oil, a salad, trail mix, and concrete (not cement). [12] A mixture can be determined to be homogeneous when everything is settled and equal, and the liquid, gas, the object is one color ...

  8. Suspension polymerization - Wikipedia

    en.wikipedia.org/wiki/Suspension_polymerization

    In polymer chemistry, suspension polymerization is a heterogeneous radical polymerization process that uses mechanical agitation to mix a monomer or mixture of monomers in a liquid phase, such as water, while the monomers polymerize, forming spheres of polymer. [2] The monomer droplets (size of the order 10-1000 μm) are suspended in the liquid ...

  9. Tint, shade and tone - Wikipedia

    en.wikipedia.org/wiki/Tint,_shade_and_tone

    In color theory, a tint is a mixture of a color with white, which increases lightness, while a shade is a mixture with black, which increases darkness. Both processes affect the resulting color mixture's relative saturation. A tone is produced either by mixing a color with gray, or by both tinting and shading. [1]
