Which of the following compounds have the same value of van't Hoff s factor \((i)\) as that of \(\mathrm{Al}_{2}\left(\mathrm{SO}_{4}\right)_{3}\) ?
- A \(\mathrm{K}_{4}\left[\mathrm{Fe}(\mathrm{CN})_{6}\right]\)
- B \(\mathrm{NaCl}\)
- C \(\mathrm{Al}\left(\mathrm{NO}_{3}\right)_{3}\)
- D \(\mathrm{Na}_{2} \mathrm{SO}_{4}\)
Answer & Solution
Correct Answer
(A) \(\mathrm{K}_{4}\left[\mathrm{Fe}(\mathrm{CN})_{6}\right]\)
Step-by-step Solution
Detailed explanation
The dissociation of compounds take place as follows: \(\mathrm{Al}_{2}\left(\mathrm{SO}_{4}\right)_{3} \longrightarrow 2 \mathrm{Al}^{3+}+3 \mathrm{SO}_{4}^{2-}, i=5\)…
