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 he 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 :math> Pb ( C 2 H 3 O 2 ) 2 ( a q ) + H 2 O ( l ) + CO 2 ( g ) → PbCO 3 ( s ) + HC 2 H 3 O 2 ( a q ) ppose an aqueous solution containing 1.25 g of lead(II) acetate is treated with 5.95 g of carbon dioxide. Calculate the theoretical yield of lead carbonate.

Solution Summary: The author explains how the theoretical yield of lead carbonate should be calculated. Theoretical yield is calculated by the amount of limiting agent.
