Statement I: Colloidal solutions are stable but the colloidal particles do not settle down. |
Statement II: Brownian movement counters the force of gravity actively on colloidal particles. |
A) Statement I is true; Statement B is true; Statement B is not a correct explanation for Statement I,
B) Statement I is true; Statement II is false.
C) Statement I is false; Statement II is true.
D) Statement I is true; Statement II is true; Statements is the correct explanation for Statement I.
Correct Answer: D
Solution :
The Brownian movement has been explained due to the unbalanced bombardment of the particles by the molecules of the dispersion medium. The Brownian movement has a stirring effect which does not permit the particles to settle and is responsible for the stability of solution.You need to login to perform this action.
