WebLyophilic (“liquid-loving”) sols are more stable and more closely resemble true solutions. Many sols are intermediate between lyophobic and lyophilic types. Compare gel. sol, in physical chemistry, a colloid (aggregate of very fine particles dispersed in a continuous medium) in which the particles are solid and the dispersion medium is ... WebLyophilic sol can be prepared by dispersion (normally by vigorous stirring of a solid in the form of gel or resin in a liquid), and condensation. During dispersion, solids are disintegrated into particles of suitable sizes to form a colloid in a dispersion medium. During condensation however, molecules or atoms are condensed into clusters ...
