- ✓$F{e_2}{\left( {S{O_4}} \right)_3}$
- C${\left[ {Fe{{\left( {CN} \right)}_6}} \right]^{4 - }}$
- D$N{H_4}{(S{O_4})_2}.FeS{O_4}.6{H_2}O$
✓
Answer
Correct option: B.
$F{e_2}{\left( {S{O_4}} \right)_3}$
b
(b) $F{e_2}{(S{O_4})_3} \to 2F{e^{3 + }} + 3SO_4^{ - 2}$.
(b) $F{e_2}{(S{O_4})_3} \to 2F{e^{3 + }} + 3SO_4^{ - 2}$.
