Question 15
H

A student adds sodium hydroxide solution to iron(III) chloride solution. An orange-brown precipitate forms.

Which ionic equation, including state symbols, is correct for this reaction?

[1]
A

Fe3+(aq)+3OH−(aq)→Fe(OH)3(aq)\mathrm{Fe^{3+}(aq) + 3OH^{-}(aq) \rightarrow Fe(OH)_{3}(aq)}Fe3+(aq)+3OH−(aq)→Fe(OH)3​(aq)

B

Fe2+(aq)+2OH−(aq)→Fe(OH)2(s)\mathrm{Fe^{2+}(aq) + 2OH^{-}(aq) \rightarrow Fe(OH)_{2}(s)}Fe2+(aq)+2OH−(aq)→Fe(OH)2​(s)

C

Na+(aq)+Cl−(aq)→NaCl(s)\mathrm{Na^{+}(aq) + Cl^{-}(aq) \rightarrow NaCl(s)}Na+(aq)+Cl−(aq)→NaCl(s)

D

Fe3+(aq)+3OH−(aq)→Fe(OH)3(s)\mathrm{Fe^{3+}(aq) + 3OH^{-}(aq) \rightarrow Fe(OH)_{3}(s)}Fe3+(aq)+3OH−(aq)→Fe(OH)3​(s)
