Subject: What are the lattice enthalpy and/or hydration enthalpy for divalent anions

Enthalpy of solution is due to the difference in lattice enthalpy and enthalpy 
of hydration, I know. But nobody seems to know the hydration enthalpies of 
carbonate and sulphate, or the lattice enthalpies of, say sodium carbonate and 
sodium sulphate. I've looked all over!
