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: \(\mathrm{Al}_{2}\left(\mathrm{SO}_{4}\right)_{3} \longrightarrow 2 \mathrm{Al}^{3+}+3 \mathrm{SO}_{4}^{2-}, i=5\)…
