Question

Given lead (ii) oxide, nitric (v) acid, sodium carbonate and water. Explain briefly how you can prepare lead (ii) carbonate. Use equations where possible.
What lesson is this
Dissolve PbO in slight excess of HNO3, evaporate to dryness, add water and Na2CO3 to precipitate PbCO3, filter and dry.
PbO(s) + 2HNO3(aq) ==> Pb(NO3)2(aq) + H2O(l)
Pb(NO3)2(aq) +Na2CO3(s) ==> PbCO3(s) + 2NaNO3(aq)
