too lazy to cehck books le,
you go to get ksp for LiBR,
then [Br][li]=ksp
[br]=[li] | s**********i 发帖数: 711 | 2 hmm... as KBr dissolvs, [Br] increases... then
[Br][Li] > ksp and LiBr precipitates... then
[Br] decreases, then more KBr dissolves... then
more LiBr precipitates... faint...

| j**i 发帖数: 419 | 3 have thought of this ah,
actually thisis kind of general chem problem bah?
not sure how they treat this le,
give some suppose..
anyway,hate to think of this le,
but obviously,
[br][li]=ksp(libr)
[Br][K]=ksp(KBr)
[Br]=[Li]+[K]
so you can get it easily,:))
(a+b)*a=changshu
(a+b)*b=changshu
a=?,b=?
now seems no problem unless you must get the KSP at the right temp ah. |
