Question

1. select the net ionic equation for the reaction that occurs when sodium hydroxide and iron(iii) chloride are mixed.

no reaction occurs
3na^{+}(aq)+3oh^{-}(aq)+fe^{3 +}(aq)+3cl^{-}(aq)→3na^{+}(aq)+3cl^{-}(aq)+fe(oh)_{3}(s)
fe^{3 +}(aq)+3oh^{-}(aq)→fe(oh)_{3}(s)
na^{+}(aq)+cl^{-}(aq)→nacl(s)
fe^{3 +}(aq)+oh^{-}(aq)→feoh(s)
3na^{+}(aq)+3cl^{-}(aq)→na_{3}cl_{3}(s)

1. select the net ionic equation for the reaction that occurs when sodium chloride and silver nitrate are mixed.

no reaction occurs
na^{+}(aq)+no_{3}^{-}(aq)→nano_{3}(s)

Explanation:

Question 1

Step1: Write the balanced molecular equation

Sodium hydroxide (\(NaOH\)) reacts with iron(III) chloride (\(FeCl_3\)):
\(3NaOH(aq)+FeCl_3(aq)
ightarrow Fe(OH)_3(s)+3NaCl(aq)\)

Step2: Write the total ionic equation

Break all soluble compounds into ions:
\(3Na^{+}(aq)+3OH^{-}(aq)+Fe^{3 +}(aq)+3Cl^{-}(aq)
ightarrow Fe(OH)_3(s)+3Na^{+}(aq)+3Cl^{-}(aq)\)

Step3: Cancel the spectator ions

Spectator ions (\(Na^{+}\) and \(Cl^{-}\)) are removed.

Step1: Write the balanced molecular equation

Sodium chloride (\(NaCl\)) reacts with silver nitrate (\(AgNO_3\)):
\(NaCl(aq)+AgNO_3(aq)
ightarrow AgCl(s)+NaNO_3(aq)\)

Step2: Write the total ionic equation

Break all soluble compounds into ions:
\(Na^{+}(aq)+Cl^{-}(aq)+Ag^{+}(aq)+NO_3^{-}(aq)
ightarrow AgCl(s)+Na^{+}(aq)+NO_3^{-}(aq)\)

Step3: Cancel the spectator ions

Spectator ions (\(Na^{+}\) and \(NO_3^{-}\)) are removed.

Answer:

\(\boldsymbol{Fe^{3 +}(aq)+3OH^{-}(aq)
ightarrow Fe(OH)_3(s)}\)
