Question

Lead carbonate (PbCO3) is a white pigment for oil painting. A chemistry student tried to make PbCO3 in the laboratory by reacting 0.125 L of 0.500 M sodium carbonate (Na2CO3) with 0.150 L of 0.190 M lead nitrate (Pb(NO3)2). The reaction of aqueous Na2CO3 and aqueous Pb(NO3)2 produces solid PbCO3 and aqueous NaNO3.

(a) Write the balanced molecular equation, complete ionic equation, and net ionic equation for the process. [Hint: Don’t forget the physical states of the reactants and products]

Balanced Molecular Equation:

Complete Ionic Equation:

Net Ionic Equation:

(b) Calculate the moles of sodium carbonate and lead nitrate. (c) Which reactant is the limiting reagent?

Answer: ___________________________________ is the limiting reagent.

(d) Determine the theoretical yield (in grams) of lead carbonate formed.
