Question
My teacher showed us these examples in class, he says he need to be able to know when something is soluble in something else but i have no idea how to know. anyone have any rules on how to know?
This is the examples he gave us:
is CsI soluble in H2O? yes
is CH3OH soluble in H2O? Yes
is CH3OH soluble in NH3? Yes
is NaCl soluble in H2O ? yes
is C6H12O6 soluble in C6H6 ? No
is C6H12O6 soluble in H2O? Yes
is C6H6 soluble in C6H12? No
is CH3OH soluble in C6H6? No
... Please help i have a test soon. he says there will be other examples on test and not the ones above...

Generally, like dissolves like.
CsI is polar. H2O is polar. yes.
CH3OH has OH. H2O has OH. yes.
I think C6H6 (is that benzene?) will dissolve in C6H12 (is that hexene). Both are non-polar solvents.
