QJEEM23Ch9670: JEE Main 2023 Chemistry - Class 12 JEEM23Ch9670 Solution: Statement I : For colloidal particles, the values of…
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
Multiple Choice Options
- A Both Statement I and Statement II are false
- B Statement I is true and Statement II is false
- C Both Statement I and Statement II are true
- D Statement I is false but Statement II is true
Step-by-Step Verified Solution
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.
This statement is true. Colloidal particles are intermediate in size between true solutions and suspensions, and their properties differ from those of true solutions. The colligative properties of colloids, such as osmotic pressure and vapor pressure, are of a smaller order of magnitude than those of true solutions with the 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.
This statement is false. For colloidal particles, the potential difference between the fixed layer and the diffused layer of opposite charges is called the electrokinetic potential or zeta potential.
