Statement I : For colloidal particles, the values of colligative properties are of small order as compared to values shown by true solutions at same concentration. Statement II : For colloidal particles, the potential difference between the fixed layer and the diffused layer of 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

1. Both statement I and Statement II are true
2. Both statement I and Statement II are false
3. Statement I is true but Statement II is false
4. Statement I is false but Statement II is true

Correct answer: Statement I is true but Statement II is false

Solution

Statement I is correct because colligative properties, which depend on the number of solute particles, are indeed smaller for colloidal solutions compared to true solutions at the same concentration. However, Statement II is incorrect as the electrokinetic potential or zeta potential specifically refers to the potential difference between the fixed layer and the diffused layer of opposite charges, not the same charges.
