Preparation of Emulsion

Preparation of Emulsion An emulsion is a dispersion of one liquid into another liquid in the form of small globules. Emulsions are generally prepared by......

Importance of Colloids

Importance of Colloids The study of colloids, lyophobic, lyophilic, molecular, or colloidal electrolytes is important not only for the satisfaction of an inquisitive mind but......

Emulsion

An emulsion is a dispersion of one liquid into another liquid in the form of small globules. Milk is a well-known emulsion. Many oils of......

Imbibition and Swelling

Imbibition and Swelling If some gelatin or agar is placed in water it first swells considerably and then either pass on to dispersion or remains......

Foam: Colloids and Emulsion

Foam A dispersion of a gas in a liquid is called Foam. Ordinary soap solutions form lather which behaves like a foam if air-bubbles entrapped......

All Gels are basically Sols but all Sols are not Gels – Explain

All Gels are basically Sols but all Sols are not Gels If the sol is concentrated and the discrete particles are present in a state......

Syneresis

Syneresis is the contraction of a gel accompanied by the separating out of the liquid. Many gels, if allowed to stand, are found to exude......

Peptization

Peptization is the process by which a coagulum or a precipitate is dispersed to a colloidal state. It is the reverse process of coagulation. It......

Electrical Double Layer

The Electrical Double Layer The electrical properties of the colloidal state of matter and other associated phenomena may be explained in terms of the existence......

Electrophoresis

Electrophoresis is a chromatography technique by which a mixture of charged molecules is separated according to size when placed in an electric field. A simple......

Colligative Properties of Colloids

Colligative Properties All molecular colloids in solution exhibit colligative properties. Since most of these colloids have high molecular masses the depression of freezing point, elevation......

Viscosity: Properties of Colloids

Viscosity Although the viscosity of dilute lyophobic colloids is slightly greater than the viscosity of the dispersion medium, concentrated lyophobic colloids can have quite high......
