Sols meaning in chemistry
WebA sol is a colloidal solution suspension of very small solid particles in a continuous liquid medium. Sols are quite stable and show the Tyndall Effect. Tyndall Effect is the scattering of visible light by colloidal particles.Artificial sols may be prepared by dispersion or condensation. Dispersion techniques include grinding solids to colloidal dimensions by … WebThe combination of the two layers of +ve and-ve charges around the sol particle was called Helmholtz double layer. According to modern view, the first layer of ions is firmly held and is termed fixed layer while the second layer is mobile which is termed as diffused layer. The combination of the compact and diffused layer is referred as the ...

WebDue to this property, they are also called reversible sols. These sols are quite stable and hence cannot be easily coagulated. b. Lyophobic colloids: The word lyophobic means liquid hating. Substances such as metals and their sulphides, etc., when simply mixed with the dispersion medium do not form the colloidal sol. These sols are called ...
WebThat means in these sols, there is little or no interaction between the dispersed phase and the dispersion medium ie, dispersed phase has little affinity for dispersion medium. These sols are easily precipitated by the addition of small amounts of electrolyte, by heating or by shaking, therefore these sols are relatively less stable than lyophilic sols.
