applications and properties of colliodal solution
Answers
Answer:
Colloids, in chemistry, are a mixture of two substances, in which one substance is divided into minute particles aka colloidal particles (ranging from 1 to 1000 nm in diameter) and dispersed or suspended over another substance. These insoluble particles are inseparable either by filtering or centrifuging. Types of Colloids are Sol, Emulsion, Foam, and Aerosol.
applications:
Medicines: Medicines in colloidal form are easily absorbed by the body tissues and hence are more effective.
Cleansing action of soap: Soap solution is colloidal in nature. It removes the dirt particles either by adsorption or by emulsifying the greasy matter sticking to the cloth
Purification of water: The precipitation of colloidal impurities present in water can be done by adding certain electrolytes like alum etc. The negatively charged colloidal particles of impurities get neutralized by the Al3+ ions and settle down and pure water can be decanted off.
Rubber industry: Latex is a colloidal solution of negatively charged rubber particles. From latex, rubber can be obtained by coagulation. Rubber plated articles are prepared by depositing negatively charged rubber particles over the article to be rubber plated by making that article an anode in a rubber plating bath.
