question 108

Multiple Choice

When a solution of ammonium chloride, NH₄Cl, is added to a solution of lead(II) nitrate, Pb(NO₃) ₂, a white precipitate of lead chloride, PbCl₂, forms. Which of the following is the total ionic equation for this reaction?

• A) 2 NH₄Cl(aq) + Pb(NO₃)₂(aq) → PbCl₂(s) + 2 NH₄NO₃(aq)
• B) 2 NH₄⁺(aq) + 2 Cl^-(aq) + Pb²⁺(aq) + 2 NO₃^-(aq)
• → PbCl₂(s) + 2 NH₄⁺(aq) + 2 NO₃^-(aq)
• C) Pb²⁺(aq) + 2 Cl^-(aq) → PbCl₂(s)
• D) Pb²⁺(aq) + Cl₂^2-(aq) → PbCl₂(s)
