A colloid is a mixture in which one substance consisting of microscopically dispersed insoluble particles are 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.
Under this definition, a colloidal dispersion is a dispersion of discrete particles of size ranging from 1 to 1,000 nm in a continuous medium. A colloidal dispersion of solid particles in a liquid medium is also called a sol.
27 wrz 2022 · In chemistry, a colloid is a mixture of tiny particles that are dispersed in another medium. The particles are microscopic in size, ranging from 1 nanometer (nm) to 1 micrometer (μm) in diameter. In contrast, particles in a solution are smaller than this size, while particles in a suspension are larger.
Any thermodynamically unstable colloidal system in which particles of colloidal size of any nature (e.g. solid, liquid, or gas) are dispersed in a continuous phase of different composition (or state) ...
20 sie 2024 · Definition of colloids. Colloids are mixtures in which one substance is dispersed throughout another substance in a fine, stable suspension; Colloids consist of a dispersed phase (the substance being dispersed) and a dispersion medium (the substance in which the dispersed phase is distributed)
4 paź 2023 · In the definition of colloid science given above, “colloid” refers to the entire system consisting of a dispersed phase and a dispersion medium (dispersant). In other words, a colloid is synonymous with a “colloidal dispersion system.”
