Linseed oil, lanolin and Glycogen attract water hence contain a hydrophobic structure but rubber does not attract water and does not contain a hydrophobic structure.
The amount of electrolyte required to coagulate a fixed amount of a sol depends upon the valency of flocculating ion.
Absorption, Tyndall effect and flocculation all are related to sol but paramagnetism is not represented by sol.
Egg is a calloid of solid and liquid; Ruby glass is a colloid of solid and solid. Milk is a colloid of liquid and liquid but chlorophyll is a complex of magnesium.
The colloidal solution of liquid in liquid is called emulsion not gel.
The ability of an ion to bring about coagulation of a given calloid depend upon both the magnitude and sign of its charge.
Traces of electrolytes are essential for stabilising the sales hence for sales destruction addition of electrolytes are required.
Lyophillic means liquid loving hence hydration is contributed toward the extra stability of lyophillic colloids.
