Answer to Question #165633 in General Chemistry for Gracie

Question

1.) Complete and balance the molecular equation for the reaction of aqueous iron(III) nitrate, Fe(NO3)3, and aqueous lithium hydroxide, LiOH. Include physical states.

2.) Enter the balanced net ionic equation for the reaction. Include physical states.

Answer 1

1.) $Fe(NO_{3})_{3}(aq)+3LiOH(aq)\rightarrow 3LiNO_{3}(aq)+Fe(OH)_{3}(s)$

Since, Fe(OH)₃ is insoluble in water,

$\therefore$ Fe(OH)₃ remains in solid state.

2.) $Fe^{3+}(aq)+3NO_{3}^{-}(aq)+3Li^{+}(aq)+3OH^{-}(aq)\rightarrow 3Li^{+}(aq)+ 3NO_{3}^{-}(aq)+Fe(OH)_{3}(s)$

$\Rightarrow Fe^{3+}(aq)+\cancel{3NO_{3}^{-}}(aq)+\cancel{3Li^{+}}(aq)+3OH^{-}(aq)\rightarrow \cancel{3Li^{+}}(aq)+ \cancel{3NO_{3}^{-}}(aq)+Fe(OH)_{3}(s)$

$\Rightarrow Fe^{3+}(aq)+3OH^{-}(aq)\rightarrow Fe(OH)_{3}(s)$
