Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding electrophoresis.
Electrophoresis is a technique used to separate particles based on their charge by applying an electric field. It is used to determine the charge on colloidal particles.
Step 2: Analyzing the options.
(A) to count number of particles in colloidal dispersions: Incorrect — Electrophoresis is not used to count particles.
(B) for stability of colloids: Incorrect — While electrophoresis can be used to study colloidal properties, it is not directly used to determine stability.
(C) to determine charge on colloidal particles: Correct — Electrophoresis is used to determine the charge on colloidal particles by observing their movement in an electric field.
(D) to determine size of colloidal particles: Incorrect — Electrophoresis does not directly measure the size of particles.
Step 3: Conclusion.
The correct answer is (C) to determine charge on colloidal particles, as electrophoresis is used for this purpose.
