Which of the following properties of colloidal solutions is due to the presence of Brownian motion?
Tyndall effect
Electrophoresis
Coagulation
Osmosis
Correct option (2) Electrophoresis
Electrophoresis is a technique used in biochemistry, molecular biology, and other fields of science to separate and analyze molecules based on their size, charge, and other physical characteristics. In this technique, an electric field is applied to a solution containing the mixture of molecules, causing them to migrate towards the opposite ends of the electric field. Electrophoresis can be used to separate a wide range of molecules, including proteins, nucleic acids, and carbohydrates, based on their charge and size. In this process, the molecules are usually first treated with a denaturing agent to remove any secondary or tertiary structure that might interfere with the separation process.
