List of practice Questions

Statement I: For colloidal particles, the values of colligative properties are of small order as compared to values shown by true solutions at the same concentration 
Statement II: For colloidal particles, the potential difference between the fixed layer and the diffused layer of the same charges is called the electrokinetic potential or zeta potential
In the light of the above statements, choose the correct answer from the options given below

The Zeta potential is related to which property of colloids?

Match List-I with List-II

	List I		List II
