Subject: Dielectric constant?

To all CCLers,

I am using MOPAC 93 to look at the heats of formation, etc. of some simple inorganic molecules and am interested in using COSMO also.  However,  the dielectric constant to use is a mystery.

Does anybody have any idea of the dielectric constant of highly caustic aluminate solutions?  These are formed with, for example,  6M NaOH and 4.4M Al metal where the resultant solution predominantly contains Al(OH)4- ions (i.e. OH- ions in tetrahedral arrangement).  Please note that these solutions do not follow ideal solution trends in this ionic concentration range!

Any references for these or similar solutions (with highly concentrated anion) would be great. 

Thanks in advance.

Terri.
