In this chapter, we will consider the nature of solutions, and examine factors that determine whether a solution will form and what properties it may have. In addition, we will discuss colloids—systems that resemble solutions but consist of dispersions of particles somewhat larger than ordinary molecules or ions.
Examples of Colloidal Systems. Table 11.4. Preparation of Colloidal Systems. Colloids are prepared by producing particles of colloidal dimensions and distributing these particles throughout a dispersion medium. Particles of colloidal size are formed by two methods: Dispersion methods: breaking down larger particles.
15 Ιουν 2023 · Colloids (also colloidal solutions or colloidal systems) are mixes of microscopically distributed insoluble particles of one material floating in another. Lets read more about colloids, its classification, preparation, examples, properties, applications and many more in this article!
19 Ιουν 2020 · A colloid is a heterogeneous mixture in which the dispersed particles are intermediate in size between those of a solution and a suspension. The particles are spread evenly throughout the medium, which can be a solid, liquid, or gas.
