How many colloids out of the following are the examples of gel:-
Paint, jelly face cream , cheese , curd , whipped cream , shoe polish .
Answers
Answer:
Colloids occur widely in nature as well as are manufactured synthetically. Since these have a wide industrial application, it is important to have a proper system for the classification of colloids. Colloids consist of a dispersed phase and a dispersion medium. They are classified on the basis of different properties of the dispersed phase and the medium. Let us learn about them here.
Classification of Colloids
Based on the Nature of Interaction Between Dispersed Phase and Dispersion Medium
Hydrophilic colloids: These are water-loving colloids. The colloid particles are attracted to the water. They are also known as reversible sols. Examples include Agar, gelatin, pectin, etc
Hydrophobic colloids: These are the opposite in nature to hydrophilic colloids. The colloid particles are repelled by water. They are also called irreversible sols. Examples include Gold sols, clay particles, etc
Colloids are common in everyday life. Some examples include whipped cream, mayonnaise, milk, butter, gelatin, jelly, muddy water, plaster, colored glass, and paper. Every colloid consists of two parts: colloidal particles and the dispersing medium.
The COLLOID is a type of mixture in which solid or liquid particles are dispersed uniformly throughout a gas, liquid or solid. It is classified into four types, EMULSION, SOL, AEROSOL, and FOAM.
Explanation:
COLLOIDS are one of the primary parts of mixture.
