Given below are two statements; one is labelled as Assertion (A) and the other is labelled as Reason(R). Assertion (A) : Lyophilic sols are more stable than lyophobic sols. Reason (R) : This is due to fact that lyophilic colloids are extensively solvated. In the light of the above statements, choose the most appropriate answer from the options given below :

Options

  1. ABoth A and R are correct and R is correct explanation of (A )
  2. BBoth A and R are correct but R is not correct explanation of (A )
  3. CA is correct but R is false
  4. DA is false but R is correct.

Correct answer

A. Both A and R are correct and R is correct explanation of (A )

Step-by-step solution

To analyze the given statements: Assertion (A): Lyophilic sols are more stable than lyophobic sols. This statement is correct. Lyophilic (solvent-loving) colloids have a strong affinity for the dispersion medium, which contributes to their stability. In contrast, lyophobic (solvent-fearing) colloids are less stable and more prone to aggregation. Reason (R): This is due to the fact that lyophilic colloids are extensively solvated. This statement is also correct. The stability of lyophilic sols comes from their solva
