Answer to Question #237480 in Chemistry for Vinny

Question

 Lead (II) trioxonitrate (V) and sodium (II) tetraoxosulphate (VI) solutions are mixed together 

to form crystals of lead (II) tetraoxosulphate (VI) coming out of solution, leaving a solution of 

sodium trioxonitrate (V) in solution. Write the molecular equation and the net ionic equation 

for the reaction.

Answer 1

Solution:

Lead(II) trioxonitrate(V) = Pb(NO₃)₂

Sodium(I) tetraoxosulphate(VI) = Na₂SO₄

Lead(II) tetraoxosulphate(VI) = PbSO₄

Sodium(I) trioxonitrate (V) = NaNO₃

Molecular equation:

Pb(NO₃)₂(aq) + Na₂SO₄(aq) → PbSO₄(s) + 2NaNO₃(aq)

Total ionic equation:

Pb²⁺(aq) + 2NO₃^-(aq) + 2Na⁺(aq) + SO₄^2-(aq) → PbSO₄(s) + 2Na⁺(aq) + 2NO₃^-(aq)

Net ionic equation:

Pb²⁺(aq) + SO₄^2-(aq) → PbSO₄(s)
