Gibb's phase rule and counting phases

[member 392791]

Hello,

I was wondering, suppose I had a mixture of a few liquids that were immiscible, say 4.

Now, when calculating the degrees of freedom, I am confused about the number of phases.

I think the number of components is 4, but the number of phases should be 1, liquid, right? Or does each component in the liquid phase count as one phase. I have seen problems that seem contradictory to what I think the answer should be

F = C - P + 2

F = 4 - 1 + 2 = 5

Four mutually immiscible liquids? Four liquid phases.
