Question

Write net ionic equations for the following metathesis (double displacement) reactions, if they occur. If no reaction occurs, write NR on the product side. All reactants are aqueous.

a. barium nitrate + sodium carbonate

b. lead (II) nitrate + sodium carbonate

c. zinc acetate + sodium carbonate 5

d. barium nitrate + sodium sulfate

e. lead (II) nitrate + sodium sulfate

f. zinc acetate + sodium sulfate

g. barium nitrate + potassium iodide

h. lead (II) nitrate + potassium iodide

i. zinc acetate + potassium iodide

Explanation / Answer

a) The complete ionic equation is:

Ba+2(aq) + 2 NO3-1(aq) + 2 Na+1(aq) + CO3-2(aq) ==> 2 Na+1(aq) + 2 NO3-1(aq) + BaCO3 (s)

The net ionic equation is:

Ba+2(aq) + CO3 -2(aq) ==> BaCO3 (s)

b)

The equation is
Pb(NO3)2 + Na2CO3 => PbCO3 (s) + 2 NaNO3

Lead (II) carbonate + sodium nitrate

Lead (II) carbonate will precipitate

c) 3 Zn(CH3COO)2 + 2 Na3PO4 >> Zn3(PO4)2 + 6 CH3COONa

d) Balanced equation:
Na?SO? + Ba(NO?)? ---> BaSO? + 2NaNO?

Net ionic equation:
Ba?
