Solution Preview

To dissolve CsI, you must break the CsI into separate ions. If you look at the electronegativity difference, you find:

Cs - 0.79
I - 2.66

Difference - 1.87

Anything above 2 is ionic. 1.87 is very close, so CsI is also ...

Solution Summary

This solution explains what attractive forces must be overcome for CsI to dissolve in HF.
