MHT CET 2025 Chemistry question
Not in JEE Main or NEET syllabus
Identify the property of colloidal solutions so that colloidal particles move freely towards respective electrodes under an applied electrical potential
Answer: (B)
Solution
Colloidal particles carry an electric charge; under an applied potential the dispersed particles migrate towards the oppositely charged electrode. This phenomenon is electrophoresis (cataphoresis): option (B). Brownian motion is the random
