Lead(II) carbonate, also called “white lead,” was formerly used as a pigment in white paints. However, because of its toxicity, lead can no longer be used in paints intended for residential homes. Lead(II) carbonate is prepared industrially by reaction of aqueous lead(II) acetate with carbon dioxide gas. The unbalanced equation is ‍Pb(C2H3O2)2(aq)+H2O(l)+CO2(g)=PbCO3(s)+HC2H3O2(aq) .Suppose an aqueous solution containing 1.25g of lead(II) acetate is treated with 5.95g of carbon dioxide. Calculate the theoretical yield of lead carbonate.

Expert Answer

Step 1

Given,

Mass of lead (II) acetate = 1.25g.

Mass of carbon dioxide = 5.95g.
