Colloids and Their Properties
A colloid is a mixture in which one substance of microscopically dispersed insoluble particles is suspended throughout another substance. Owing to this peculiar structure of colloid, it has varied physical and chemical properties. Colloidal Properties can be divided into following categories Physical Properties Colligative Properties Optical Properties-Tyndall effect Mechanical Properties - Brownian Movement Electrical Properties Physical Properties of Colloidal Solutions · Stability: Colloids are relatively stable in nature. The particles of the dispersed phase are in a state of continuous motion and remain suspended in the solution. · Filterability: Silver colloidal products require specialized filters known as ultrafilters for filtration. They readily pass through ordinary filter papers without yielding any residue. · ...
