Why does the acidity of #HX# #"(X=halogen)"# INCREASE down the Group?
This is conceived to be an entropy effect..........
We interrogate the equilibrium:
Both the hydronium ion, and the halide anion are solvated species. That
On the other hand, hydrogen fluoride is the weakest acid of the hydrogen halides. Here, the
Certainly fluoride salts give rise to basic solutions:
How is this consistent with the prior argument?
