Answer
Dissociation of $Fe(NO_3)_3$ in water:
$Fe_3(NO_3)_3(s) -^{H_2O}- \gt Fe^{3+}(aq) + 3N{O_3}^{-}(aq)$
Work Step by Step
- When strong electrolytes are added to water they dissociate, which means that they will divide, producing their ions.
1. Identify the cation and the anion in $Fe(NO_3)_3$
- Cation : 1 $Fe^{3+}$
- Anions: 3 $N{O_3}^{-}$
2. Write the equation for the dissociation:
$Fe_3(NO_3)_3(s) -^{H_2O}- \gt Fe^{3+}(aq) + 3N{O_3}^{-}(aq)$
** Remember: the ions are dissociated in an aqueous solution, so, their state symbol is "(aq)".
