I am looking to investigate the relation between experimental enthalpies of solution and theoretical enthalpies of solution calculated using theoretical equations for the lattice enthalpy and hydration enthalpy for ionic salts. I read that because of the covalent nature of ionic salts with a lower difference in electronegativity, the experimental lattice enthalpy of these salts is actually greater than would be expected theoretically. Would this be worth investigating?

To investigate this, I am looking for public databases with data for the solution enthalpy and ionic radii of ionic salts however I cannot find any other than the CRC handbook for physics and chemistry (and only the 85th version; would it be better to get a more recent version or should these data be the same in more recent versions?). I would like to use more than one database so could someone please let me know of any other public databases with these data?

You can refer to the NIST Chemistry WebBook for thermodynamic data by species or reactions. I also found a database for lattice enthalpy here. For ionic radii, you can refer to this database.

  • $\begingroup$ I am trying to find data for the enthalpy of solution specifically but I can't find it anywhere other than the CRC handbook. The NIST chemistry webbook does not seem to include it either. Do you know where I could find data for the enthalpy of solution? $\endgroup$

  • $\begingroup$ I made a brief search and found similar results...Maybe you should look for research papers on specific compounds instead. $\endgroup$
