Question

Write the Molecular, Ionic, Net Ionic Equation, Spectator Ions for:

1. AgNO₃ + NaCl

2. AgNO₃ + Na₂SO₄

3. Pb(NO₃)₂ + NaCl

4. Pb(NO₃)₂ + Na₂SO₄

5. Ba(NO₃)₂ + Na₂SO₄

Answer 1

1. AgNO₃(aq) + NaCl(aq) -----------> AgCl(s) + NaNO3(aq) molecular equation

Ag^+(aq) + NO₃^-(aq) + Na^+(aq) + Cl^-(aq) -----------> AgCl(s) + Na^+(aq) + NO3^-(aq) ionic equation

spectator ions Na^+(aq) , NO3^-(aq)

Ag^+(aq) + Cl^-(aq) -----------> AgCl(s)   net ionic equation

2. 2AgNO₃(aq) + Na₂SO₄ (aq)--------------> Ag2SO4(s) + 2NaNO3(aq)   molecular

     2Ag^+(aq) + 2NO₃^-(aq) + 2Na^+(aq) + SO₄ ^2-(aq)--> Ag2SO4(s) + 2Na^+(aq) + 2NO3^-(aq) ionic

        spectator ions Na^+(aq) , NO3^-(aq)

2Ag^+(aq) + SO₄ ^2-(aq)---> Ag2SO4(s)   net ionic equation

3. Pb(NO₃)₂ (aq)+ 2NaCl(aq)----------> PbCl2(s) + 2NNO3(aq)   molecular

    Pb^2+(aq) +2(NO₃)^- (aq)+ 2Na^+(aq) + 2Cl^-(aq)-----> PbCl2(s) + 2Na^+(aq) + 2NO3^-(aq) ionic

    spectator ions Na^+(aq) , NO3^-(aq)

Pb^2+(aq) + 2Cl^-(aq)-----> PbCl2(s)        Net ionic equation

4. Pb(NO₃)₂(aq) + Na₂SO₄(aq) ---------->   PbSO4(s) + 2NaNO3(aq)

Pb^2+(aq) +2(NO₃)^-(aq) + 2Na^+ (aq) +SO₄^2-(aq) ---------->   PbSO4(s) + 2Na^+(aq) + 2NO3^-(aq)

   spectator ions Na^+(aq) , NO3^-(aq)

Pb^2+(aq)   +SO₄^2-(aq) ---------->   PbSO4(s)    net ionic equation

5. Ba(NO₃)₂(aq) + Na₂SO₄ (aq) ----------> BaSO4(s) + 2NaNO3(aq)

    Ba^2+(aq) + 2(NO₃)^-(aq) + 2Na^+(aq) + SO₄ ^2-(aq) -----> BaSO4(s) + 2Na^+(aq) + 2NO3^-(aq)

   spectator ions Na^+(aq) , NO3^-(aq)

   Ba^2+(aq) + SO₄ ^2-(aq) -----> BaSO4(s)    Net ionic equation
