Which one of the following electrolytes has the same value of van't Hoff factor \((i)\) as that of \(Al_2(SO_4)_3\) (if all are \(100\%\) ionised)?

  1. A \(Al(NO_3)_3\)
  2. B \(K_4[Fe(CN)_6]\)
  3. C \(K_2SO_4\)
  4. D \(K_3[Fe(CN)_6]\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(K_4[Fe(CN)_6]\)

Step-by-step Solution

Detailed explanation

\(\mathrm{Al}_{2}\left(\mathrm{SO}_{4}\right)_{3} \rightarrow 2 \mathrm{Al}^{3+}+3 \mathrm{SO}_{4}^{2-}, i=5\) \(\mathrm{Al}\left(\mathrm{NO}_{3}\right)_{3} \rightarrow \mathrm{Al}^{3+}+3 \mathrm{NO}_{3}^-, i=4\)
