Hello, I have learned the concept of miscibility with simple 2 substances, and even found a guide about online with solvent polarities and miscibility chart

http://www.chemical-ecology.net/java/solvents.htm

So, for example, Acetone and Hexane are miscible, so they "mix."  Methanol and Hexane are immiscible, so they form 2 layers.

However my question is about more advanced cases, such as mixing say in equal parts, Acetone:Hexane:Methanol  what will the results be?  Acetone is miscible with both Hexane and Methanol so I not sure what the result should be?  If anyone could steer me in the right direction on this or give any input I would be very appreciative!  Thank you

I would say this "mixture" won't "mix". I mean, miscibility is not about chemical reactions, so the structural characteristics that make two substances not been miscible are still there anyway.

Would an emulsion be possible?

I don't know the answer   was hoping someone else does.  So, to simply the question

A = Hexane
B = Acetone
C = Water
A <-> miscible with B
B <-> miscible with C
A not miscible with C

what happens when all 3 mix?  i guess i could try to setup an experiment I'm not sure if I have all the ingredients though..

This is quite difficult to predict, as the final effect depends on the intermolecular forces and their interplay. My bet is that you have to either find literature information on such a system behavior, or test it experimentally.

Exactly. Tertiary phase diagrams is something to look for.

Incidentally some prediction is possible from binary experiments. Look up activity coefficients. Immiscibility is generally a non ideality of solutions.
