\( \text{PO}_4^{3-} > \text{SO}_4^{2-} > \text{Cl}^- > [\text{Fe(CN)}_6]^{4-} \)
\( \text{Cl}^- > \text{SO}_4^{2-} > \text{PO}_4^{3-} > [\text{Fe(CN)}_6]^{4-} \)
\( \text{SO}_4^{2-} = \text{Cl}^- = \text{PO}_4^{3-} = [\text{Fe(CN)}_6]^{4-} \)
\( [\text{Fe(CN)}_6]^{4-} > \text{PO}_4^{3-} > \text{SO}_4^{2-} > \text{Cl}^- \)

The Correct Option is
D
Solution and Explanation
The flocculating power of ions depends on their charge according to the Schulze-Hardy rule. Higher charged ions have greater flocculating power.

The critical micelle concentration (CMC) of a soap solution is \( 5 \times 10^{-4} \, \text{mol L}^{-1} \). Identify the correct statements about this solution.
[I.] The micelle is stable if the soap solution concentration is \( 10^{-7} \, \text{mol L}^{-1} \)
[II.] The micelle is stable if the soap solution concentration is higher than \( 5 \times 10^{-4} \, \text{mol L}^{-1} \)
[III.] Micelles are also known as associated colloids.
