Question

the preparation of lead sulphate from lead carbonate a two step process. a) what is the first step that is required to prepare lead sulphate from lead carbonate?

Answer 1

To prepare PbSO4 from PbCO3 first react the PbCO3 with nitric acid to get lead nitrate
PbCO3 (s) + 2HNO3 (aq) -----> Pb(NO3)2 (aq) + CO2 (g) + H2O(l)
The lead nitrate is then reacted with any soluble sulphate, e.g. Na2SO4, to precipitate lead sulphate:
Pb(NO3)2 (aq) + Na2SO4(aq) ---> PbSO4(s) + 2NaNO3 (aq)

Answer 2

Answer:pbco3

Explanation: cut chase

pbco3 + 2hno3 -> pb(no3)2 + co2 + h20

pb(no3)2 + na2so4 -> pbso4 + 2nano3
