Re: lithium bromide solubility ?

I understand your point, but I thought to add a common example where
the difference rather than the similarity is more enphasized. In case
of silver halide, there is about 1000-fold differences in the
solubilities of AgCl, AgBr, and AgI, in descending order, in
water. AgI is about a million times insoluble than AgCl. AgF is
soluble and very different from the other silver
halides. Incidentally, AgBr and AgI differ slightly in electric and
physical properties (including lattice distance) and this difference
is very effectively used in film emulsions to achive good grain to
speed ratio since about 1990.
