Question

give the net ionic equation for the reaction (if any) that occurs when aqueous solutions of iron(ii) chloride and lead(ii) nitrate are mixed.
o pb²+ (aq) + 2 cl (aq) → pbcl₂ (s)
o no reaction occurs.
o fe²+ (aq) + 2 no3 (aq) → fe(no3)2 (s)
o fe²+ (aq) + 2 cl (aq) + pb²+ (aq) + 2 no3 (aq) → pbcl₂ (s) + fe²+ (aq) + 2 no3 (aq)

Explanation:

Step1: Write the chemical equation

The chemical equation for the reaction between iron(II) chloride (\(FeCl_{2}\)) and lead(II) nitrate (\(Pb(NO_{3})_{2}\)) is \(FeCl_{2}(aq)+Pb(NO_{3})_{2}(aq)\to Fe(NO_{3})_{2}(aq)+PbCl_{2}(s)\)

Step2: Write the total ionic equation

\(Fe^{2 +}(aq)+2Cl^{-}(aq)+Pb^{2 +}(aq)+2NO_{3}^{-}(aq)\to Fe^{2 +}(aq)+2NO_{3}^{-}(aq)+PbCl_{2}(s)\)

Step3: Write the net - ionic equation

Cancel out the spectator ions (\(Fe^{2+}\) and \(NO_{3}^{-}\)). The net - ionic equation is \(Pb^{2 +}(aq)+2Cl^{-}(aq)\to PbCl_{2}(s)\)

Answer:

\(Pb^{2 +}(aq)+2Cl^{-}(aq)\to PbCl_{2}(s)\)
