Question

Determine net ionic equations, if any, occuring when aqueous solutions of the following reactants are mixed.

Select "True" or "False" to indicate whether or not the stated reaction (or "no reaction") correctly corresponds to the expected observation in each case.

A) True False Nickel(II) chloride and lead(II) nitrate; Pb2+(aq) + 2Cl-(aq)—-> PbCl2(s)

B) TrueFalseCalcium acetate and sodium carbonate; Ca2+(aq) + CO32-(aq)——> CaCO3(s)

C) True False Sodium phosphate and potassium nitrate; No reaction occurs.

D) True False Ammonium sulfate and barium nitrate; Ba2+(aq) + SO42-(aq)—>

BaSO4(s)

E) TrueFalse Copper(II) sulfate and ammonium carbonate; Cu2+(aq) + CO32-(aq) ——> CuCO3(s)

Answer 1

A) True Nickel(II) chloride and lead(II) nitrate; Pb2+(aq) + 2Cl-(aq)—-> PbCl2(s)

NiCl2(aq) + Pb(NO3)2(aq) ---------------> Ni(NO3)2(aq) + PbCl2(s)

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

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

B) True Calcium acetate and sodium carbonate; Ca2+(aq) + CO32-(aq)——> CaCO3(s)

Ca(CH3COO)2(aq) +Na2CO3(aq) ----------> CaCO3(s) + 2CH3COONa(aq)

Ca^2+(aq) + 2(CH3COO)^-(aq) +2Na^+(aq) + CO3^2-(aq) ----------> CaCO3(s) + 2CH3COO^-(aq) + 2Na^+(aq)

Ca^2+(aq) CO3^2-(aq) ----------> CaCO3(s)   net ionic equation

C) False Sodium phosphate and potassium nitrate; No reaction occurs.

Na3PO4(aq) + 3KNO3(aq) -------------> K3PO4(aq)+ 3NaNO3(aq)

D) True Ammonium sulfate and barium nitrate; Ba2+(aq) + SO42-(aq)—>BaSO4(S)

E) True Copper(II) sulfate and ammonium carbonate; Cu2+(aq) + CO32-(aq) ——> CuCO3(s)
