Name the kind(s) of attractive forces that must be over come in order to do the following:
dissolve CsI in liquid HF
I believe the first two forces are present and then one of the ion forces?© BrainMass Inc. brainmass.com March 21, 2019, 7:09 pm ad1c9bdddf
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 ...
This solution explains what attractive forces must be overcome for CsI to dissolve in HF.
