Hi Again Folks
Does anyone know if you can convert lead carbonate to lead sulphate and how?
Cheers Tim

It depends on purity of solid lead carbonate, but always is better to get solution before precypitation, so dissolve PbCO3 in HNO3, then (eventually after filtration) add H2SO4.

Direct reaction with Lead(II) Carbonate with Sulphuric Acid will result in Lead(II) Sulphate formed will form a coat on the uncreacted Lead(II) Carbonate, thus preventing furthur reaction.
