Final answer:
A colloid mixture is a dispersion of particles of one substance throughout another substance, which can be further classified as sols, gels, aerosols, or emulsions. Sol-gel transformation is the process by which a sol transforms into a gel, resulting in the formation of a three-dimensional network.
Step-by-step explanation:
Colloid Mixture:
A colloid is a mixture in which particles of one substance are dispersed evenly throughout another substance. Colloids can be classified as sols, gels, aerosols, or emulsions depending on the nature of the substances involved. For example, Jell-O is a gel, which is a colloidal dispersion of a liquid phase throughout a solid phase.
Sol-Gel Transformation:
Sol-gel transformation refers to the process by which a sol (a colloidal dispersion) transforms into a gel (a semisolid sol). This transformation occurs when the liquid phase of the sol is absorbed by the solid particles, resulting in the formation of a three-dimensional network. The gel is characterized by its high viscosity and inability to flow readily.
Three important keywords in this answer are: colloid mixture, sol-gel transformation, and gel.
