Quantitative analysis on mixture of Pb(NO3)2 and Na2CO3

Accepted Answer

Quantitative analysis of a mixture of Pb(NO3)2 and Na2CO3 can be carried out by gravimetric analysis. The Pb(NO3)2 can be precipitated as PbCO3 by adding a solution of Na2CO3 to the mixture. The PbCO3 precipitate can then be filtered, washed, dried, and weighed to determine the amount of Pb(NO3)2 in the mixture. The Na2CO3 can then be determined by difference.
