You also need to do a bit of work on where all the water drained to.

My memory of inorganic chemistry ain't what it used to be but I didn't think lead carbonate was soluble - google reveals:

All carbonates, sulfites and phosphates are insoluble EXCEPT those of ammonium and Alkali metal (Group IA) cations.

and the alkali metals are:

Lithium
Sodium
Potassium
Rubidium
Cesium
Francium
